Humidity Probe (SpyderWeb Series)

This optional humidity probe is an accessory made specifically for the Herpstat SpyderWeb series of thermostats. Its 12-foot long cable is used to measure the humidity in your reptile's tank. 

• Measures the humidity in your tank.
• Can be used as a supplemental humidity probe or a replacement.
• Compatible with SpyderWeb series of Herpstats and standard models that have firmware version 5.0 or greater (see the full list below).
• The cable is 12 feet long.

Compatible with:

All Herpstat 1 SpyderWeb

All Herpstat 2 SpyderWeb

All Herpstat 4 SpyderWeb

Herpstat 1 (firmware 5.2 or greater)

Herpstat 2 (firmware 5.1 output #1 only, 5.2 or greater works on both outputs.)

Herpstat 4 (firmware 5.0 or greater)

Herpstat 6 (firmware 5.0 or greater)

Important notes: Each output on a Herpstat device has a single function. This means you cannot set the output for temperature control AND humidity at the same time. So if you purchase this for a Herpstat 1 or Herpstat 1 SpyderWeb, you will only be able to monitor/control humidity and not have control of temperature with the Herpstat since it only has one output and one probe jack.

Redline 1/2 models flashed to firmware 5.2 or greater to work with this new humidity probe will deactivate the red led glow system.

Tip: To check the firmware version on your unit, unplug it for ten seconds and plug it back in. The unit will display the firmware version on startup.
