Durable, compact design

The Micro IV is compact, robust and very easy to use. It is designed to be used in the harshest environments. The Micro IV includes a set of rubber boots to withstand hard knocks and drops.

Widest Range of sensors

Micro IV detectors are available for use with a wide range of long-lasting, interchangeable smart-sensors for the detection of O2, H2S, CO, NH3, SO2, Cl2, ClO2, PH3, NO2, HCN, HCl, ETO, HF, O3, NO, H2 and more.

Easy Operation

The Micro IV keeps gas detection simple. Most day-to-day functions are controlled with a single button, and calibration is fully automatic. Simply select the calibration mode from the keypad, attach the adapter and flow gas to the sensor. The GfG Autocal® feature automatically makes the adjustments and updates the information in the instrumentís on-board memory.

Up to six months of battery life

The Micro IV delivers up to 3,000 hours of continuous operation from a single off the shelf AA alkaline battery. Battery replacement, when needed, can be completed in less than 30 seconds and requires no tools.

Clip-on attachment

The Micro IV comes with a heavy duty alligator clip that allows the detector to be conveniently clipped on to clothing and if so desired near the breathing zone.

Optional motorized pump

The Micro IV is available with an optional motorized pump to allow sampling from a remote location. The motorized pump may also be used in extraordinary harsh conditions, such as extreme heat, where it may be desirable to protect the instrument under protective clothing; using a tube the pump can draw air samples from the breathing zone.

Large graphic display

The Micro IV detector features a large backlit easy-to-read graphic display that provides a continuous readout for the sensor installed. By pressing a single button additional information such as Peak, STEL and TWA readings my be displayed.

Audible, vibrating and visual alarms

The Micro IV detector features a loud alarm (95db at 12 inches), a built-in vibrating alarm and a bright multi-directional visual LED alarm light.

Lifetime warranty

The Micro IV carries a lifetime warranty on non-consumable components and two or more years of warranty on most sensors. Select sensors such as O2, H2S, and CO carry a full three year warranty against failure.

DS220 docking station

The Micro IV is available with a six position fully automatic docking station. The docking station makes bump test and calibration even easier and all maintenance records are stored automatically. The docking station fully test sensor response, alarms and other functionality.
