Introduction: 

GAS ANALYSERS TGA-1 accurately measures the concentration of a Oxygen gas in parts per million (ppm)/parts per billion (ppb)/%. These gas analyzers use electrochemical/NDIR/ PID/Pallister sensors which have an enviable reputation for reliability, stability, and rugged design having an output linearly proportional to the concentration level of the gas.

Application:

Gas Analysers TGA-1 find application in - Process Control, Quality Control, Area Surveillance Safety in work areas of Factories and Research institutions

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.

Application :

• a personal safety gas monitor which is small, lightweight, versatile & as per is 5780 for safety monitoring.
• gases monitored: co, h2s, so2, no, no2, cl2, br2, nh3, co2, voc, o2, o3, h2, a3h3, hcn, ph3, cocl2, hcl, eto, clo2 etc.

THE PERSONAL AIR SAMPLER Model PAS25 consists of a mini pump driven by a D.C. motor working on a 6 volt rechargeable battery. These work continuously for up to 10 hours between charging. If required, the air sampler can be used, while charging by 220 V AC mains supply. The screw arrangement allows variation of flow rates between 0.5 and 2.5 litres/minute. A flow meter is mounted on the face of the box.

Pulsation dampers are internally fitted on the inlet and outlet gas circuit to smoothen the air flow. The pump unit is fitted into a M.S. case of compact size. The sampler unit can be kept on a flat surface for stability at the breathing zone level of the worker to take STEL(15 mins.)/ TWA-TLV (8 hour) measurements. The air sampler is supplied with battery charger in a carrying case.

Applications:

These instrument is applicable for three things, 1) TWA-TLV/STEL, 2) Dusts, Fumes, Mists and 3) Gases, Vapours and Solvents within factories, plants, government organization, research institutions etc.

1) TWA-TLV/STEL Limits values are statutory requirements. By sampling the breathing air, the short term exposure limit can be determined. Otherwise using the sampler for an 8 hour shift the TWA - TLV value can be ascertained for the contaminant.

2) Dusts, Fumes, Mists For collection of toxic dusts e.g. arsenic, cadmium, beryllium, carbon black, cobalt, copper, lead, manganese, nickel rhodium, silver or tin, the use of a filter is the simplest. Many oxides or metal fumes, produced by casting, welding or burning, may be collected on a filter for analysis.

3) Gases, Vapours and Solvents Using the sampler, a convenient collecting method is by adsorption tubes or detector tubes suitable to the gases & vapors to be analyzed or de-adsorbtion for chromatograph analysis of the adsorbent. Also, for adsorption into a liquid contained in a bubbler for chemical analysis

The PERSONAL AIR SAMPLER Model PAS25 consists of a mini pump driven by a D.C. motor working on a 6 volt DC rechargeable battery.

This work continuously for up to 10 hours between charging. If required, the air sampler can be used, while charging by 220 V AC mains supply.

The screw arrangement allows variation of flow rates between 0.5 and 3.0 liters/minute. A flow meter is mounted on the face of the box.

Pulsation dampers are internally fitted on the inlet and outlet gas circuit to smoothen the air flow. The pump unit is fitted into a M.S. case of compact size.

The sampler unit can be kept on a flat surface for stability at the breathing zone level of the worker to take STEL (15 Mins.)/TWA - TL V (8 hour) measurements. The air sampler is supplied with a battery charger in a carrying case

PRIMA MGM-4P is a microprocessor based, handheld, convenient & portable multi gas monitor designed for the monitoring of four gases, % OXYGEN, ppm CARBONMONOXIDE, ppm HYDROGEN SULPHIDE & % LEL of a COMBUSTIBLE GAS.

It is fitted with highly reliable and reputed sensors. The instrument works on disposable dry batteries, optionally a rechargeable battery can be provided. The instrument is capable of SAMPLING, VIEWING and DATALOGGING of INSTANTANEOUS VALUE, STEL AND TWA readings. Logged data can be downloaded to a computer for printing or storage along with the date and time of the readings. Two Alarms, both audible and visual are provided.
