The 913-M Low Pressure Probe for the Imperial® iManifold™ can transmit up to (3) points of data including pressure (-14.5 to 232 psig) and up to (2) channels of temperature via two plug-in thermistor temperature probes (not included). This probe can also function as a ZigBee repeater for other wireless probes to increase overall transmission distance for the iManifold system. The 913-M can be used to calculate evaporator superheat and show box temperature with optional accessory probes, could be used to measure oil pressure or simply used as a low pressure probe for remote measurement. Use the 913-M with a 914-M (high pressure probe) to monitor an additional compressor or multiple compressors in rack systems. 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*, a 6" long hose (1/4" straight x 1/4" 45 degree). * Can also be powered by user supplied micro USB power supply.
