911-M iManifold Wireless Temperature and Humidity Probe
(w/ WetBulb Calculation in App)
The 911-M temperature and humidity probe for the iManifold can transmit up to (4) points of wireless data including air temperature, air relative humidity, and up to (2) channels of temperature via (2) plug-in thermistor temperature probes (not included). The iManifold app will automatically calculate the wetbulb and display it for you. (When you have the air temperature and the humidity from the probe, the app calculates the wetbulb.)
The 911-M has a magnetic handle to hold it to sheet metal duct while the measurement is being made. This probe can also function as a Zigbee repeater for other wireless probes to increase the overall transmission distance for the iManifold system.
The 911-M can be used by itself with an optional accessory pipe probe and air probe to calculate target superheat and temperature split for fixed metering device systems or can be used with a second 911-M to calculate total capacity (BTUh), sensible capacity, latent capacity, dehumidification and temperature split in real time with user input airflow. If electrical current and voltage are input into the application, the EER can also be calculated.
The probe cannot be used without the iManifold®(or iConnect®) as the iManifold® iConnect® is the communications hub for interfacing with the smart device application. A maximum of 12 probes can be connected. Includes 2 AAA batteries or can be powered by user supplied micro USB power supply.
For best "hold" on the magnets: Drill a hole exactly 11/16" in diameter and they will hold. A 3/4" diameter hole will not hold nearly as well as the magnets are so close to the sides of the probe.
