Temperature Sensors, Humidity Sensors and Water Sensors.

Temperature Sensors.

The T8800 from GRI is a single sensor programmable temperature monitoring security device. Unlike its big brothers, the ThermStat 3 and 4 where four individual sensors are used, the T8800 has only one sensor. The single temperature sensor is housed in the appliance (T8800) or can be ordered with a connected remote probe (T8800R). The memory in the T8800 is non-volatile because all temp trip limits are set with a small screw driver. No typical software program is required.

  • Low Cost
  • Non-Volatile Memory
  • Single Sensor or a Remote Probe up to 500
  • Min - Max Temperature Range No Probe -
    -10ºF to 176ºF
  • Min - Max Temperature Range With Probe -
    -40ºF to 185ºF
  • Operates with 7.5 VDC minimum to 15 VDC maximum

H8800 Humidity Sensor.

The H8800 from GRI is a single sensor programmable humidity monitoring security device. Unlike its 1st cousin, the T8800, used for temperature sensing, the H8800 has one sensor to detect and report relative humidity. The single humidity sensor is housed in the appliance (H8800) or it can be ordered with a remote probe (H8800R). The memory in the H8800 is non-volatile.
  • Low Cost
  • Non-Volatile Memory
  • Single Sensor or a Remote Probe up to 500
  • Min - Max Temperature Range No Probe -
    -10ºF to 176ºF
  • Min - Max Temperature Range With Probe -
    -40ºF to 185ºF

12 Volt DC Under Carpet Water Sensor.

Undetected water damage such as that caused by leaking
pipes or corroded water heaters cost homeowners tens of thousands of dollars each year. Such repairs are time consuming and costly to correct. Applications could include computer room sub-floor areas, telephone equipment rooms, bathrooms, laundry rooms, any areas adjacent to a water storage tank or piping. Also evaporative air conditioners, drip pans, overflows and/or drains.
  • Will detect any conductive non-flammable liquid.
  • Ideal anywhere water damage could occur
  • Automatic Reset.
  • Available in gray only.
  • 6 foot jacketed lead standard.
  • Custom lead lengths available.
  • Available in 5 VDC, 12 VDC and 24 VDC.
  • New 24 Volt AC Water Sensor.

Absence of Water Sensor.

The GRI 2808 Absence of Water Sensor is a totally new innovative design that helps monitor the level of water and other non flammable liquids. The GRI 2808 is submersible, fully self-contained and responds reliably to the absence of or the presence of water. The GRI 2808 fits a multitude of applications in a wide range of environmental landscapes.

The GRI 2808 microprocessor conducts a sample every 2.5 minutes. Optional custom sample rates are available. Call the factory for more information.

The C-form relay gives the installer greater flexibility for triggering wireless and hardwired communication devices.
  • Microprocessor Controlled.
  • Detects Absence or Presence of Liquid.
  • Powered by 5 Year Lithium Battery.
  • Standard Sample Rate is Once Every 2.5 Minutes.
  • Form C Relay.

 Liquid Level Sensor Product Specification pdf.

The G.R.I. 2826 Sensor was designed in response to a direct request for a small electronic sensor capable of detecting non-volatile liquids in remote hard to reach locations. The sensor, in conjunction with your favorite wireless transmitter, can be used to detect and report the encroachment of non-volatile liquids into an isolated sensitive location.
  • Detects Non-Volatile Liquids
  • For Use With Wireless Transmitters
  • Microprocessor Controlled
  • Installs Easily
  • C Form Relay Contacts
GRI manufacturers high quality temperature sensors, water sensors, humidity sensors and safeties for hvac.  G.R.I.s quality assurance department inspects every devise before it leaves each phase of production to make certain the quality is there. Our 0 defect program is the standard our employees follow. They know quality cannot be inspected IN - we build with quality parts, quality people and quality standards.
