This product has been discontinued and is no longer available. In many cases we can still service and calibrate it. Talk to our team about spares or alternatives.
The D-Guard (Digital Guard) is a digital fixed gas detector using an advanced processor and program logic pre-programmed for many gas types, with a permanently backlit graphic display and 4-20 mA output.
KEY BENEFITS
- Zero stability logic for accurate readings
- One-man non-intrusive calibration
- Graphical backlit display
- No-alarm calibration mode
- One board suits all gases and ranges

Digital Gas Detection with One-Board Flexibility
The D-Guard (Digital Guard) uses an advanced processor and program logic to make selecting a reliable detector simple. Its electronics monitor sensor output trends and calculate accurate, stable readings that are shown on a permanently backlit graphic display and transmitted using the industry-standard 4-20 mA.
A single card suits all applications, easily configured for different gases, ranges and sensor styles, which greatly simplifies stock holding for customers in remote locations. Each card is simple to upgrade as needs change, with spare resources for future features.
Housed in a UV-stable, IP66 carbon-filled anti-static Nylon enclosure designed for the harshest offshore conditions, the D-Guard offers non-intrusive one-man calibration, a no-alarm calibration mode that locks the output during service, and an isolate feature for maintenance.

It offers non-intrusive one-man calibration with no screwdrivers, meters or special programming tools required, and a no-alarm mode that locks the output at zero until calibration is finished.
A single configurable card holds program logic for many gas types, ranges and sensor styles, so customers in remote locations do not need to stock many different detectors.
It detects gases including ammonia, carbon monoxide, chlorine, hydrogen, hydrogen sulfide, nitric oxide, nitrogen dioxide, phosphine, sulfur dioxide, ethylene oxide, ozone and oxygen.
The Standard (65-1010-XX), Relay version (65-1011-XX) and D-Guard S with sounder and strobe (65-1012-XX), where XX denotes gas type.
Two years on O2, CO, H2S and electronics, and one year on all other sensors.
