in material and workmanship, when subjected to normal, proper and
intended usage by properly trained personnel, for the period of time set
forth in the product documentation, published specifications or package
inserts. If a period of time is not specified in Seller’s product
documentation, published specifications or package inserts, the warranty
period shall be one (1) year from the date of shipment to Buyer for
equipment and ninety (90) days for all other products (the "Warranty
Period"). Seller agrees during the Warranty Period, to repair or replace, at
Seller's option, defective Products so as to cause the same to operate in
substantial conformance with said published specifications; provided that
(a) Buyer shall promptly notify Seller in writing upon the discovery of any
defect, which notice shall include the product model and serial number (if
applicable) and details of the warranty claim; (b) after Seller’s review, Seller
will provide Buyer with service data and/or a Return Material
Authorization (“RMA”), which may include biohazard decontamination
procedures and other product-specific handling instructions; and (c) then,
if applicable, Buyer may return the defective Products to Seller with all
costs prepaid by Buyer. Replacement parts may be new or refurbished, at
the election of Seller. All replaced parts shall become the property of Seller.
Shipment to Buyer of repaired or replacement Products shall be made in
accordance with the Delivery provisions of the Seller’s Terms and
Conditions of Sale. Consumables, including but not limited to lamps,
fuses, batteries, bulbs and other such expendable items, are expressly
excluded from the warranty under this warranty.
Notwithstanding the foregoing, Products supplied by Seller that are
obtained by Seller from an original manufacturer or third party supplier are
not warranted by Seller, but Seller agrees to assign to Buyer any warranty
rights in such Product that Seller may have from the original manufacturer
or third party supplier, to the extent such assignment is allowed by such
original manufacturer or third party supplier.
In no event shall Seller have any obligation to make repairs, replacements
or corrections required, in whole or in part, as the result of (i) normal wear
and tear, (ii) accident, disaster or event of force majeure, (iii) misuse, fault
or negligence of or by Buyer, (iv) use of the Products in a manner for which
they were not designed, (v) causes external to the Products such as, but not
limited to, power failure or electrical power surges, (vi) improper storage

with equipment or software not supplied by Seller. If Seller determines
that Products for which Buyer has requested warranty services are not

covered by the warranty hereunder, Buyer shall pay or reimburse Seller for
all costs of investigating and responding to such request at Seller's then
prevailing time and materials rates. If Seller provides repair services or
replacement parts that are not covered by the warranty provided in this
warranty, Buyer shall pay Seller therefor at Seller's then prevailing time and
materials rates. ANY INSTALLATION, MAINTENANCE, REPAIR,

Introduction
The Thermo Scientific™ PDM3700 Personal Dust Monitor (PDM),
manufactured for miners, incorporates a real-time particulate monitor that
measures respirable coal dust mass concentration, shift exposure, and
accumulated exposure in real time (Figure 1–1). The monitor is suitable for
personal and area monitoring in underground mines, or other occupational
environments with elevated particulate concentrations. The PDM3700 is a
wearable device that sets up quickly, delivers accurate results, recharges
quickly and is easily serviced.
The PDM3700 contains all the hardware and software necessary to
measure and store ambient particulate mass concentration. The mass
measurement is a filter-based direct mass monitoring instrument using
proprietary TEOM and momentum compensation technologies. The flow
control system maintains a constant volumetric flow at 2.2 l/min and total
filter loading to 6 inches-Hg (20.32 kPa).

Introduction
Advanced Features
1-2 PDM3700 Instruction Manual Thermo Fisher Scientific
The user interface includes membrane switches and a top-mounted
character display that provides shift exposure information and status codes.
The high contrast display provides basic data and statistics for the system,
including status conditions. An additional PC-based user interface is
provided through WinPDM communication software. The PDM3700 is
powered by one internal lithium-ion battery assembly. See Table 1–1 and
Table 1–2 for the PDM3700 system specifications.

PDM3700 Specifications
Flow Rate 2.2 l/min ±2.5% when calibrated at set point*
Run Time: PDM Minimum of 12 hours**
Humidity: PDM 0–100% RH, condensing and non-condensing
Humidity: Charging Station 5–95% RH, non-condensing
Altitude -3,500 to 10,000 feet
Temperature: Sampled Air -5 to +105 °F (-20 to +40 °C), typical range is 32–85 °F
(0–30 °C)
Temperature Shock 40 °C/min
Temperature: Charging 32–105 °F (0 to 40 °C)
*The PDM 3700 must be calibrated at the mine location to achieve optimum results. A flow audit may be
performed prior to an initial calibration, but the results may not meet the ±2.5% accuracy specification. If
audit results are outside the ±2.5% accuracy requirement, perform a flow calibration.
**Minimum 12-hour shift possible with unit undergoing warm-up on charger. Warming up unit off charger
will reduce maximum shift run time.

The PDM3700 battery charger (Figure 1–2) is a separate unit that connects
to the PDM3700 and provides a charging station as well as communication
functions. A separate external power cord and communication/charge cable
must be installed to operate the charger (Chapter 2).
Figure 1–2. PDM3700 Charger
Note The charger supplied with the PDM3700 is not the same charger
that was supplied with the PDM3600. The PDM3600 included the
integrated cap lamp in the device and needed a charging circuit to charge
that battery. This charger circuit was removed from the charger supplied
with the PDM3700. The charger supplied with the PDM3700 will not
work with the PDM3600, however the charger supplied with the
PDM3600 will work with both the PDM3700 and the PDM3600. The
difference being that when charging the PDM3700 the cap lamp LED on
the charger will not function. ▲
Note Always charge the PDM3700 in fresh air in Battery Charging
stations as defined in 30 CFR 75.340 or fresh air above ground. ▲

Introduction
Advanced Features
1-4 PDM3700 Instruction Manual Thermo Fisher Scientific
The PDM3700 offers a number of features to provide superior data
quality, ease of use, and flexibility for the user. The following is a partial list
of the instrument’s advanced features:
●30-minute mass concentration measurement in the range of 0.1 to 10
mg/m3(cumulative shift average)
●Accuracy for mass measurement: 25% with 95% confidence, as
compared to gravimetric reference samplers using similar cyclones, in
the range of 0.2 mg/m3and greater
●Display resolution of 0.01 mg/m3
●Starting with a new TEOM filter, the batteries allow a 12-hour run, up
to a loading of 5 mg
●User-definable manual and programmed sample collection options,
based on worker shift lengths
●Capable of indoor and outdoor use
●One internal lithium-ion battery pack; full charge in 6 hours from a
depleted charge state (Note: the charging light may take up to 8 hours
to turn from blinking green to solid green as part of an enhanced
charging top-off feature)
●Lightweight - approximately 4.4 pounds (2 kg)
●Meets MSHA intrinsic safety requirements
The WinPDM software for the PDM3700 is a Microsoft Windows-based
program. Users should have a general understanding of their personal
computer (PC) and of the Windows operating system, including entering
and editing text, and opening, closing and saving files.
