1. CAUTIONS
Users of the portable field equipment should read and understand this document in its entirety. Failure
to comply with the instructions given in this user guide could cause irreparable damage to the
equipment (Handheld instrument, digital sensor and PHOTOPOD).
This equipment must only be used under the conditions described in this user guide. Use under any
other conditions might result in the malfunction of the multiparameter portable device-
Sensor/PHOTOPOD measurement chain.
2. GENERAL POINTS
2.1 Product overview
The multiparameter portable device of measuring and data logging equipment can be used in
conjunction with one or more digital sensors to measure the following parameters:
- Temperature,
- Dissolved oxygen as % saturation, in mg/L and/or ppm,
- Turbidity in NTU, FNU or mg/L,
- Conductivity (compensated at 25°C), salinity and TDS-KCl,
- Induction conductivity (compensated at 25°C), salinity, non-compensated conductivity
- pH,
- Redox.
The multiparameter device unit can also be combined with the PHOTOPOD to operate as a digital field
photometer.
In total, the various versions of the PHOTOPOD can measure more than 50 parameters, including:
NH4+, NO3-, PO4, COD, NO2-, Ptotal, SO42-, Turbidity, Fe, Cu, Mn, Cl2, CN-, ClO2, TH, TA, TAC, N2H4,
DEHA, Fe, Br2, Cu, Mn, Mo, SiO2, Zn, Benzotriazole, phosphonates…
2.2 –Main functions of the portable digital unit
The multiparameter portable unit can measure both physico-chemical and photometric parameters.
a)- Automatic recognition of the type of sensor connected, and its serial number.
The calibration coefficients associated with the parameters measured by the sensor, and the historical
data from calibrations performed previously, are stored within the sensor and are instantly available
to the portable device.
The default parameters for each type of sensor are measured and displayed instantaneously by the
portable device.
Automatic recognition of the PHOTOPOD, and of its version and serial No.
b)- Automatic refreshing of the measured value for all the selected parameters.
c)- Operation in photometer mode, with selection of the analysis method (including performing blank
measurements).
d)- Three data logging modes:
- Snapshot recording mode: saves the value of one of the active parameters at the instant
when a keypad command is pressed,
- Automatic recording mode, started manually when a keypad command is pressed,
- Automatic recording mode, programmed by setting the start and end date and time of the
measurement campaign.
The saved data is managed by creating a file named by the user (location of the measurement
campaign, sample name, etc.).

e)- Each measurement saved in a specific file can be viewed via the RESULT menu
either by scrolling through the data or by selecting the measurement number.
f)- Valuable traceability feature: the user’s identity can be specified. This information is added to the
saved data, and notably to the historical data for calibration operations.
g)- The unit switches to standby mode automatically to increase its autonomy.
2.3 –Additional features
a)- High level of equipment protection: IP67 (waterproof) guaranteed when new, prior to any user
intervention on the unit (e.g. to replace the batteries)
b)- The equipment operates autonomously, powered by four AA alkaline batteries or by 4 AA NiMH
rechargeable batteries (provided as an option, with charger cable) or by an external 12V power source
(external power supply cable available as an option).
c)- Saved data can be retrieved from the device (via a USB link) and viewed on a PC after installing the
proprietary software.

3.3 - Description of the sensors
3.3.1 Oxygen/temperature sensor –PODOA-PODOB
The OPTOD dissolved oxygen sensor applies the luminescence-based optical measurement technology
approved by ASTM International Method D888-05.
An oxygen-sensitive layer is illuminated by a diode that emits blue light. The sensitive layer reacts by
emitting red light (fluorescence). The intensity of the emitted light and the delay between the
absorption and emission of this light vary depending on the concentration of oxygen.
This optical technology requires only very few consumables: no changing of membranes, no
electrolyte.
The DO disk, which contains the sensitive material, typically requires changing once every 2 years.

OPTOD sensor maintenance:
The OPTOD sensor must be kept clean, especially the DO disk and its surrounding area. Any trace of
biofilm might induce a measurement error.
After each use, rinse the sensor before storing it.
If any dirt builds up on the membrane, clean the head of the sensor with a little warm, soapy water. A
sponge may be used, but do not use the "scouring" face of a dishwashing sponge.
Then rinse the sensor before storing it.
If the sensor is due to be used again shortly, place a wad of cotton wool, moistened with a few drops
of water, in the storage bag to keep the disk hydrated. If the sensor is stored for longer periods the
disk will dry out. In this case, ensure that the disk is rehydrated sufficiently before use so that the
sensor is fully operational.
Oxygen calibration:
Using a clean sensor, occasionally check the 0% Sat value by immersing the sensor in a sulphite solution
in water (sulphite concentration < 2% by weight). If there is a zero error, perform a complete
calibration of the sensor.
Caution: do not leave the sensor in contact with the sulphite solution for more than 1 hour.
The 2-point calibration is performed using a sulphite solution (for the offset) then, after rinsing and
drying, the sensor’s gain is determined by exposing the sensor to humid, oxygen-saturated air.
Place the sensor over a surface of water without getting in touch with the water.
Temperature calibration:
The temperature sensor is calibrated annually, and is a 2-step process:
- step 1 (offset): the sensor is placed in a container containing a water bath and ice,
- step 2 (gain): the sensor is placed in a medium (air or water in a temperature-controlled bath) at a
known temperature. This temperature may be measured using a certified thermometer.
Changing the stainless steel sieve cap with integrated disk:
If measurement drift is detected while using the equipment, clean and then calibrate the sensor.
If calibration is not possible for whatever reason, change the membrane holder containing the sensitive
material.
Unscrew and remove the sensor's stainless steel sieve, clean the optical window with soapy water and
a sponge, then finish by wiping with a little alcohol to remove any smears on the window.
Then fit a new sieve onto the head and screw it on slowly so that the air inside the sensor can escape
via the threads.
Then perform a 2-point calibration procedure: 0% Sat and 100 % in air.
CAUTION: ONLY remove the sieve if necessary, and screw it back on slowly.

3.3.2- Turbidity/temperature sensor –PNEPA-PNEPB
The measuring principle used by the turbidity sensor is based on nephelometry: a diode emits infrared
light (880 nm) and an IR receiving diode, set to one side at an angle of 90°, detects the amount of
scattered light (standardized measurement). The sensor can be calibrated using a formazine standard.
This optical technology is very economical and requires very little maintenance and no consumables
(simply gentle cleaning of the optical components).
