Honeywell TS33F Remote Temperature and Humidity Sensor with Probe

Honeywell weather stations and digital clocks that display outdoor temperature or outdoor temperature and humidity require wireless remote sensors to sense the weather data and transmit it to the station or clock. These stations and clocks include the necessary sensor, but some stations and clocks can receive signals from up to three sensors, in which case any additional sensors desired must be ordered separately. 

The Honeywell TS33F is white with a red LED on the front that flashes once when temperature data is being transmitted and twice when the battery gets low. The LCD panel above the LED shows the temperature in your choice of °C or °F and the humidity in percent. The cable and probe are white to match the remote.

The probe on the TS33F is removable, so this remote can sense temperature either by means of the probe or, with the probe removed, by means of an internal sensor. Please be aware that the probe senses temperature only, not humidity. Because the probe and cable are waterproof, the.TS33F can be used for many applications, including pool, pond, or spa, refrigerator or freezer, and greenhouse or soil. Also, in really cold weather, you could use the TS33F to sense outdoor temperature by extending the probe out of a window with the remote safely indoors (in which case the humidity reading would be for indoor humidity).

The TS33F is well suited to extended low temperature operation. When temperatures below freezing are expected for an extended time period, you can install lithium AA batteries instead of alkaline. Lithium cells provide superior performance in sub-zero temperature conditions. The display may fade in severe cold, but this is normal for liquid crystals, and the display should reappear when temperatures warm to freezing and above.

In the battery compartment of the TS33F are a channel 1, 2, or 3 selection switch, a switch that selects °C or °F for the transmitted and displayed temperature, and a Reset button that you press with a paper clip or similar tool after changing the batteries.

The TS33F Temperature and Humidity Sensor with Probe can rest on a horizontal surface, or it can be wall-mounted via a keyhole slot on the back. The remote transmits 433 MHz signals and operates on two AA alkaline or lithium batteries (not included). Average battery life is approximately 1 year. The LED on the TS33F flashes once when it transmits a temperature reading to the main unit. When it flashes twice, this indicates a low battery condition.

Note on Remote Sensor Compatibility: You can use a Honeywell temperature and humidity sensor with a Honeywell product that displays temperature only, in which case humidity is not displayed for the temperature-humidity sensor's channel. Similarly, you can use a Honeywell temperature-only sensor with a Honeywell product that displays both temperature and humidity, but the humidity display for the temperature sensor's channel will be blank.

For years, Honeywell has been the name to trust for high-quality indoor environmental controls. Now you can have the same high quality in environmental monitoring. For superior environmental instrumentation, why not go with Honeywell, the name you know you can depend on?
