CO / H2S Dual Sensor (GT-43 Only)

73-0023 Gaswatch 3 Portable Gas Monitor, CO, Electrochemical sensor, with alligator clip by RKI Instruments

The GasWatch 3 is the world's smallest and lightest single-gas monitor. Weighing just 1.6 ounces, its compact form affords great comfort and flexibility in how you choose to wear it. It can be worn on your wrist as a watch, or clipped into your breathing zone on your lapel, hard hat or other safety equipment with its alligator clip.

The 5 different GasWatch 3 models can protect you from oxygen deficiency [GW-3(O2)], exposure to carbon monoxide [GW-3(CO)] or exposure to hydrogen sulfide [GW-3(H2S)]. A hydrogen compensated model [GW-3(C-)] can protect those who work in steel mills, refineries or other environments where hydrogen is present from carbon monoxide exposure. The dual sensor model [GW-3(CX)] can simultaneously protect you from oxygen deficiency and carbon monoxide exposure.

A small, field-replaceable, coin-type lithium-ion battery gives the GasWatch 3 up to 4,000 hours of continuous operation. The hydrogen compensated CO can operate up to 2,500 hours, and the dual sensor CO/O2 model will get up to 2,000 hours of continuous operation.

The great battery life coupled with a 3-year warranty* gives the GasWatch 3 tremendous value and a low cost of ownership.

Note: *2-year for galvanic sensor on the O2 model

Features

• 5 versions to choose from: CO, H2S, O2, CO/O2, or H2 compensated CO

753A Refrigerant Leak Detector by Test Products International

The 750a features 400 hour sensor life under normal use; a spare sensor is included with each instrument for a total of 800 hours of continuous use and can detect leaks as small as 0.1 ounces per year (R134a / R22).

Whether testing for leaks in air conditioning, refrigeration, or automotive AC, the versatile 700 series spans the diverse needs of technicians, refrigeration engineers, and maintenance personnel around the globe. From freezer coils to heat pumps, experience fast, reliable results that save you both time and money.

The TPI 750a is a state-of-the-art refrigerant leak detector capable of detecting all halogen based gases. The internal diaphragm pump and unique sensor design provide fast and reliable gas sensing. Selectable sensitivity combined with an adjustable tick rate will allow any service professional to pinpoint those tough to find leaks even in contaminated environments.

Sensor life can be extended by fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests; clean or replace the tube regularly.

Even though TPI refrigerant leak detector sensors are very durable and can last up to 400 hours, sensor life can be aided by press fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests. Clean or replace the tube regularly.

Features

• Detects all existing refrigerants and blends including 404A, PURON 410A and *R-507 (AZ50)
• 400 hour individual sensor life; a spare sensor is included with each instrument for a total of 800 hours of continuous sensor use.
• Fast response; Begin testing immediately after power on
• 0.1 ounce per year sensitivity
• Pump driven for increased sensitivity with blended refrigerants
• Pinpoint small leaks easily by elimination of background concentration with fully adjustable tic rate
• Visual indicators for power, tic rate and battery replacement
• Optional earphone attachment

Applications

• Check for leaks in refrigeration systems
• Test for leaks in air conditioning systems and cooling units
• Find leaks in automotive air conditioning systems

Standard Accessories

• Sensor: A721
• Instruction Manual: 753a Instruction Manual
• Soft Case with strap (A755)
