TRIPLE PLUS + - Ranges of 0-2000 ppm, 0-10,000 ppm, 0-100% LEL, or 0-100% Volume - Multi-gas unit that simultaneously monitors, displays, and alarms for one to four gases with many different interchangeable, 'smart' electrochemical sensors available. These units are housed in an ultra durable case that is virtually unbreakable, highly water resistant, dust proof, and RF resistant. This is the only unit that would float if dropped accidentally in water! The large digital display with backlight shows the levels of the gases and the push button menu for the advanced microprocessor's features which is password protected. There is the option of a built-in air pump, internal datalogger, and more.

TETRA - Ranges of 0-1000 ppm or 0-100% LEL - These new, portable multi-gas monitors are offered for several different gas sensor configurations with advanced features at a very low price. One large button is used for easy operation with an auto zero self check function when switched on. All units come standard with a large LCD backlight display, internal datalogger, built-in air pump (or diffusion option), internal vibrating alarm, rechargeable Li-ion battery pack and charger (or optional Alkaline battery pack). Optional software package allows for full configuration control, user calibration, and access to the Event log file.

NEW GASMAN - Ranges of 0-1000 ppm or 0-100% LEL - These single gas, personal size monitors replaced the original Gasman (1991-2000) and Gasman II (2000-2009) units. This version is the lightest and lowest cost but is also the most advanced, flexible, durable, and compact! Each unit offers easy one button operation, a large backlit digital display, peak hold, IP65 & IP67 water and dust protection, with multiple levels of built-in audio, visual, and vibrating alarms including TWA in toxic versions. Replaceable batteries last up to two years in oxygen and toxic versions. Rechargeable batteries and a charger are used for combustible versions. There is no built-in air pump but each unit comes standard with a flow cap and internal event logging with optional communication software.

K6050 & KG6050 - Ranges of 0-1% to 0-100% Volume - Analyzers utilizing Thermal Conductivity to accurately measure the changes of one constituent in binary or pseudobinary gas mixtures with a non-depleting katharometer sensor that requires no maintenance. A built-in sample pump means that samples can be drawn from low pressure sources or can be naturally aspirated. True portability is from sealed rechargeable batteries, which offer 6 hours continuous operation. Extended operation is possible by running the unit with the battery charger connected. The whole instrument is housed in a tough ABS case with a carrying handle. A large, alphanumeric LCD shows measured values and also displays messages and prompts for the menu-driven configuration and calibration routines.

SERIES U - Ranges of 0-1000 ppm to 0-5000 ppm or % LEL - Unique, patented sensors are utilized that are unaffected by moisture, temperature change, or poisons. Units are available for many different common or exotic gases in low levels for leaks or in very high measuring ranges that most or no other gas monitors can handle. All units are equipped with adjustable audio/visual alarms. The portable version has the sensor attached to the end of a probe connected by cable to controller unit with choice of analog or digital display. There is no built-in air pump or internal datalogger option.

GASMASTER - TXGARD SERIES - Ranges of 0-2000 ppm or 0-20,000 ppm (50% LEL) - The Gasmaster Series of single and multi-channel control units can be connected to the TXgard Series of toxic and oxygen gas remote sensors. The TXgard Series are available in several versions for almost any application. The Gasmaster Series offers digital display, built-in battery back-up, continuous output signals, common and individual dual level alarms, relay contacts, and can be used with most other remote sensors that transmit a 4-20 mA signal.

GASMASTER - FLAMGARD SERIES - Range of 0-100% LEL - The Gasmaster Series of single and multi-channel control units can be connected to the Flamgard Series of combustible gas remote sensors. The Flamgard Series are available in several versions for almost any application. The Gasmaster Series offers digital display, built-in battery back-up, continuous output signals, common and individual dual level alarms, relay contacts, and can be used with most other remote sensors that transmit a 4-20 mA signal.

GUARDIAN SERIES - Ranges of 0-200 ppm to 0-2000 ppm - Digital display wall mounted controllers with one to four remote sensors for detecting, alarming and controlling toxic or oxygen leaks quickly by using proven electrochemical sensor technology. There are displays and audio/visual alarms on the controller provided for each remote sensor with accompanying internal relay contacts. The controller and remote sensors are enclosed in a NEMA 4X fiberglass enclosure. These units are easy to install and operate.

MD-16 - Range of 0-200 ppm - Single gas, non-display, all-in-one sensor/controller wall mounted units for continuous monitoring toxic or oxygen leaks enclosed in a NEMA 4X fiberglass enclosure. A green LED confirms that the unit is functional. Two alarms are provided, with each indicating a specific concentration of gas with audio and visual indications and internal relay contacts. This unit is extremely easy to install and use with low maintenance. The alarms can be tested, silenced, and reset remotely by shining a flashlight on the front panel.

SERIES U - Ranges of 0-1000 ppm to 0-5000 ppm or % LEL - Unique, patented sensors are utilized that are unaffected by moisture, temperature change, or poisons. Units are available for many different common or exotic gases in low levels for leaks or in very high measuring ranges that most or no other gas monitors can handle. All units are equipped with adjustable audio/visual alarms. The wall mounted versions have a contact relay as standard and are available in single or multi-channel configurations. The electrical classification of the remote sensors is explosion proof under Class 1, Division 1, Groups B, C, and D hazardous atmospheric areas and can be wired up to 2000 feet away. Recorder outputs and dual alarms are available.

CEA 420 SERIES - Ranges of 0-1000 ppm to 0-5000 ppm or % LEL - The same exact, patented sensors as in the Series U are used but in the explosion proof housing is a built-in amplifier/transmitter. These stand alone units only need 12 VDC, 24 VDC, or AC power and will continuously transmit a linear 4-20 mA signal to any existing controllers or PLC that can interpret these signals. Digital display is the only available option since there are no alarms, relays, or other types of outputs available with these units.
