TRIPLE PLUS + - Range of 0-1 ppm - 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.

NEW GASMAN - Range of 0-20 ppm - 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.

GASMASTER - TXGARD SERIES - Range of 0-1 ppm - 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.

GUARDIAN SERIES - Ranges of 0-3 ppm to 0-80 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.
