The most commonly selected options have been checked as defaults. If your preferred configuration is not selectable below, then please contact Neodym.

Please note: Lead time on electrochemical sensors is 3-5 weeks. All other lead times are 1-2 weeks.

Sensor Type & Target Gas

MOS (metal oxide)
Hydrogen (0-1K ppm)
Methane (0-1K ppm)
ECHEM (electrochemical)
Oxygen (0-30%vol.)
TCOND (thermal conductivity)
Hydrogen (0-100%vol.)
Helium (0-100%vol.)

Action Levels)
Alarm Concentration:     percent of total sensing range (10 to 100)
Warning Concentration:     percent of total sensing range (10 to 90, 0=warning not used)

Please note:

For oxygen sensor the warning level is the deficiency point and the alarm level is the richness point.

Recommended alarm points for safety applications:
Oxygen: warn: 65% of range (19.5% vol.), alarm: 80% of range (24.0% vol.)

Output Signal Type and Action

   0-5 VDC (0.5V offset, 1000 steps of 5mV each, one step per resolution unit)
   Step function (voltage encoded states: 0V=error, 1.25V=normal, 2.5V=warning, 3.75V=alarm)    TTL, Normally-High, Auto (self-clearing)
   TTL, Normally-Low, Auto (self-clearing)
   TTL, Normally-High, Latching (pushbutton/power-cycle reset)
   TTL, Normally-Low, Latching (pushbutton/power-cycle reset)

If TTL output, signal is triggered by: Warning State and/or Alarm State

Relay Type and Action

   Normally-Closed, Auto (self-clearing)
   Normally-Open, Auto (self-clearing)
   Normally-Closed, Latching (pushbutton/power-cycle reset)
   Normally-Open, Latching (pushbutton/power-cycle reset)

If used, relay is triggered by: Warning State and/or Alarm State

Note: Normally-closed relay facilitates power failure detection.

Alarm Beeper

80 dB at 30 cm alarm beeper: None     include beeper

Error Handling

If sensor fails or operating temperature is out of bounds, signal this:

   Audio-visually only     by activating alarm devices(s) (fail safe)

Overexposure Handling (MOS sensors only)

If sensor is subject to overexposure damage, handle this by:

   setting maximum sensitivity     by setting persistent error condition (fail safe)

Input Power Supply

   4.75 - 5.25 VDC     7 - 40 VDC     7 - 60 VDC


none (circuit board only)
anodized aluminum enclosure

Sensor Extension

Extend sensor head  meters from control unit. (0 = no extension, 9 meters max.)

Please note: Sensor extension is not available for the oxygen sensor.

Interface harness

   Include Molex 15cm color-coded wire interface harness

AC/DC Power Suppy

   Include 110VAC-to-9VDC power supply (6 feet cord, Molex connector)
