The PRIMA OXYGEN METER Model OM-A is an INTRINSICALLY SAFE instrument which measures % Oxygen in workplace atmosphere. The instrument display is driven by the electrochemical sensor output, which is of the order of 1.5 milliamps in Air with voltage of 0.8 volts in open circuit.
These weak output values make the sensor intrinsically safe per IEC. There is no battery power required to drive the galvanometer and therefore no spark can be generated whatsoever. It has an analog display.
OA – Oxygen Analyser
The PRIMA Model OA is Microprocessor based Trace Oxygen analysers offer all the desired features of an highly advanced instrument at affordable prices.
TGA-1- Gas Monitor (O2 /CO2/ CO / SO2 / NO2 / NO / HC)
TOXIC GAS ANALYSERS TGA-1 accurately measure the concentration of a particular gas in parts per million (ppm) / %.
These toxic gas analysers use Electrochemical / NDIR / PID sensors which have an enviable reputation for reliability, stability and rugged design having an electrical output linearly proportional to concentration level of the gas.
SGA-1P – Personal Safety Gas Detector
The SGA-1P is personal gas alarms which are handheld. The instruments work on a 6 volts disposable dry cell. They have two alarms both audible and visual and low battery indication.
SGA-1P are fitted with highly reliable & reputed electrochemical sensors. A belt clip is provided for hands free use.
SGM-1P – Personal Safety Gas Monitor
The PRIMA SGM -1P is A PERSONAL SAFETY GAS MONITOR which is small, lightweight, versatile and as per IS:5780 for Intrinsic Safety monitoring any one gas from the table below.
It weighs less than 210 grams and 10 x 7 x 3½ cm in size. It is durable and hardy enough for use in harsh environments meeting the standards of Environmental Tests under IS:13109.
TX-24V – Loop Powered Transmitter
Often it is more cost effective to replace a sensing head with one which is pre-calibrated at a testing station, thus reducing disruption of the measuring system.
Prima offers such an industry standard 4-20 mA transmitter consisting of an electrochemical sensor, its associated circuitry and in a weather-proof / flame proof (DGMS/CMRI approved) housing.
