Overview - We stock a range of instruments for gas monitoring.

Stand Alone Detectors

Delphian's Stand Alone Sensors can be used with virtually any
controller, datalogger or computer-based data management systems that accepts a 4-20 mA input. Delphian's Stand Alone Sensors are available for every sensor sold by Delphian, sensors include:

Catalytic Bead Sensors
Semiconductor Sensors
Electrochemical Sensors
Infrared Sensors
Paper Tape Detectors (not manufactured by Delphian)

One Touch Calibration Stand Alone Gas Monitoring System

The SafeCAL module installs in a Class ABCD (FMRC) conduit box with a glass dome. A Delphian sensor attaches through gold plated keyed connectors and a weather-proof fitting for easy installation and reliable operation. The entire system is sealed. All calibration is completed without opening the explosion-proof housing. SafeCAL will endure temperatures from -40oC (-40oF) to +85oC (+185oF). It will operate even when its conduit box is one third full of water. Suited for use with the following sensors:

Catalytic Bead Sensors
Semiconductor Sensors
Electrochemical Sensors
Infrared Sensors
Paper Tape Detectors (not manufactured by Delphian)

Delphian Determinator (Fixed Point Infrared) sensor

The Delphian Determinator (Fixed Point Infrared) sensor is a smart infrared hydrocarbon gas detector. It has no moving parts. It displays gas concentrations up to and above 100% LEL including over-range (above 120% LEL) concentrations up to 999% LEL. It can determine which hydrocarbon gas is being detected and transmit a 4-20 mA signal proportional to the LEL concentration of that gas or vapor. The Determinator displays the correct LEL as well as the gas detected on its five digit LED display. It can be set to show up to three gas alarm levels. An optional four-relay alarm module (SLAM) can be connected directly to the Determinator so that local alarms can be actuated in the event of a gas alarm or failure. The detector head is designed so that all normal operations, including checking calibration and changing alarm levels can be done in the field without declassifying the area. The built-in self test continuously monitors the hardware and software. Minor fault conditions are displayed on the LED display. Four informational and six possible critical malfunctions are transmitted on the 4-20 mA line. Standard RS 422/485 output is also available. Using a separate module, the Determinator can be interfaced with most digital protocols including HART and Fieldbus.

Delphian Remediator (Fixed Point Infrared) sensor

The Delphian Remediator (Fixed Point Infrared) sensor is a smart infrared hydrocarbon gas detector. It has no moving parts. It is a percent by volume detector. In all other respects it is the same instrument as the infrared Determinator above.
