personnel in a safe area thus user adjustment is not required.
• Replacement or charging of the equipment is only permitted in a non-
hazardous area.
• Only GMI replacement parts should be used.
• Instrument must be re-charged in a safe area before use. Refer to
Chapter 6 : ‘RECHARGE BATTERY’.
• If the instrument detects gas, follow your own organisation’s procedures
and operational guidelines.
• Gas can be dangerous and care should always be taken in its use.
• This equipment is designed and manufactured to protect against other
hazards as defined in ATEX Directive 94/9/EC and UL913 (7th Edition).
Any right of claim relating to product liability or consequential damage to any

AREAS OF USE
Exposure to certain chemicals can result in a loss of sensitivity of the flammable
sensor. Where such environments are known or suspected it is recommended
that more frequent response checks are carried out. (Refer to Chapter 3:
‘MANUALBUMP TEST’). Chemical compounds that can cause loss of sensitivity
include Silicones, Lead, Halogens and Sulphur.
Do not use instrument in potentially hazardous atmospheres containing greater
than 21% Oxygen.
SPECIAL CONDITIONS OF USE
No precautions against electrostatic discharge are necessary for portable
equipment that has an enclosure made of plastic, metal or a combination of
the two, except where a significant static generating mechanism has been
identified.Activities such as placing the item in a pocket or on a belt, operating
a keypad or cleaning with a damp cloth, do not present a significant electrostatic
risk. However, where a static-generating mechanism is identified, such as
repeated brushing against clothing, then suitable precautions shall be taken,
e.g. the use of anti-static footwear.
STORAGE, HANDLING AND TRANSIT
The instrument is designed to handle harsh environments. The instrument is
sealed to IP67 and, if not subjected to misuse or malicious damage, will provide
many years of reliable service.

iii
COPYRIGHT
The instrument can contain electrochemical sensors. Under conditions of
prolonged storage these sensors should be removed. The sensor contains
potentially corrosive liquid and care should be taken when handling or disposing
of the sensor, particularly when a leak is suspected.
WARRANTY
The GMI PS200 instrument has a warranty against faulty goods or workmanship
of 2 years. Consumable and Mechanical parts, e.g. pump, sensors, filters,
etc., are not included in this. These are covered under GMI standard warranty
conditions. For details, please contact GMI Ltd (UK).

INTRODUCTION
1.1 GENERAL DESCRIPTION
The GMI PS200 series combines quality, ruggedness and
advancedtechnologyina user friendly,portablegasdetector.
It is compact, lightweight, water resistant, extremely robust
andissuitablycertifiedto recognised International Standards.
The PS200 is designed for confined space monitoring, for
example,insewers, undergroundpiping, or withintanks and
otherpersonal monitoring applications.With audible, visual
andvibrating alarms,it providesearly warningof dangerous
gaslevels.
The instrument is available as either a pumped or diffusion
model and is powered by an internal Li-ion (lithium ion)
rechargeablebatterywithminimumoperatingtimeof14hours
for non-pumped operation (8 hours for pumped operation).
Maximumrecharge timeis 4hours.
Operatedvia two push buttons, this instrument providesthe
user with a simple to use, yet state-of-the-art, gas detector.
(Fig.1-1).
The PS200 series features high visibility LED’s, a display
that changes colour from green to red when an alarm is
present, a sounder with a 90dB minimum output and a
vibratingalarm.Userscanbeconfidentthat,shouldgaslevels

1.3 DATALOGGING
Data logging is a standard feature of all PS200 series
instrumentsandallowsgasmeasurements,eventlogs,bump
tests and calibration details to be automatically stored and
later downloaded to a Personal Computer (PC) via a USB
connection.
Manualdatalogging can alsobeachieved simplyviaa single
press of the Left Hand (LH) button .

USERHANDBOOK
Theinstrument can storein excessof 24 hoursof readingsat
a recording interval of 1 minute, 180 On / Off event logs and
alarms,180 bump testlogs and 8 calibrations.
1.3.1 Archiving Stored Readings
Stored readings can be downloaded from the PS200 series
instrument to a PC, using the standard charging / comms
cable and additional software. Contact the GMI Sales
Departmentforfurther details.
1.4 FILTERS
