Biosystems Multi Gas Detectors
IQ Docks™ For Automated Bump Test & Calibration
Sperian Instruments now Honeywell Analytics

Any Biosystems instrument can be purchased separately or put together as a complete kit which includes the detector, all standard accessories, comprehensive training CD video, sample draw kit, calibration gas, regulator and foam lined carrying case. Optional accessories include motorized pumps, Datalink Software kits for use with datalogging designs, and much more.

Biosystems PhD6

The Biosystems PhD6™ multi-gas detector for hazardous gas monitor has it all - 5 sensor ports, up to 6 channels of detection and over 19 sensor options including electrochemical, LEL, PID, and infrared (IR). Adds infrared CO2, LEL &PID VOC detection. The PhD6 day-to-day operations are controlled entirely through the mode button. A status bar on the display with easy-to-recognize icons gives the user immediate access to everything from time to calibration status. Built-in and easy-to-navigate menus give advanced users the ability to configure the detector in the field. Interchangeable alkaline and Li-Ion rechargeable battery packs have run times as long as 24 hours

Reduce your calibration gas use by up to 60% and reduce labor expenses by cutting down on the time needed to perform calibrations. Use with the IQ6 Docking Station™, a fully automated bump test, calibration, meter diagnostics and data download center which also provides automatic record keeping.

Honeywell IQ Force

The Honeywell IQ Force multi-gas detector displays real time readings for up to 4 gases including oxygen (O2), combustible gases (%LEL), hydrogen sulfide (H2S) and carbon monoxide (CO). Add an optional pump, docking station and software to provide a more comprehensive IQ Management System solution. IP65/67 water rating.

Biosystems Discontinued Models

The Biosystems Cannonball^3™  portable gas detector is also designed to measure oxygen, combustible gas and up to two toxic gases. It offers the ease of use and dependability of our other gas detection products with the additional advantage of being housed in a gasketed, waterproof case designed to take on the roughest industrial environments and survive. Available with ppm readout of hydrocarbons for use in landfills or industrial plants.

The Biosystems PhD Lite monitors up to four atmospheric hazards simultaneously: oxygen, combustible gas, carbon monoxide, and hydrogen sulfide. The PhD Lite allows you to choose specific sensors for the detection of CO or H₂S when you have only one toxic hazard to deal with; or choose the duel channel "Duo-Tox" sensor to measure both CO and H2S when both hazards are simultaneously present. All procedures necessary for day-to-day operation, including fully automatic calibration adjustment, are controlled through a single button. Each set of three disposable AA batteries provides up to 9 hours of continuous operation.

The Biosystems PhD⁵ monitors up to five atmospheric hazards simultaneously: oxygen, combustible gases and up to three toxic gasses. Choose from a wide variety of toxic sensors; including Biosystems' innovative new "Duo-Tox" two-channel CO/H2S sensor to measure both carbon monoxide and hydrogen sulfide when both hazards are present without cross interference. The instruments are equipped with the TouchID™  automatic memory input system, which uses small memory buttons to store user identification, location information & language preferences. Download stored information easily with a touch of a button. Buttons may be attached to worker ID badges, key rings or permanently mounted near frequently entered confined spaces.

The Biosystems PhD Ultra measures oxygen, combustibles, and up to two toxic gases. All normal procedures including automatic calibration adjustment are controlled with a single button. The instrument automatically logs gas readings, user and location ID and other important information. The easy-to-use PhD Ultra is housed in a rugged, compact case with choice of snap-in NiCad or alkaline battery packs.
