Digital Temp-Alert (TA-2HLD)

[PN# ** DISCONTINUED **]

Part #M-001-0001. Single zone electronic Temp alert with professional appearance - Microprocessor controlled.


The model TA-2HLD operates from 12, 24V AC/DC, features a professional appearance with large LCD display and separately adjustable high and low set points. Standard unit monitors temperature from +32 to +130 deg F (0 to 55 deg C). Optional probes are available for wider temperature ranges. (see Accessory Options) If the monitored temperature rises above the high set point, a SPST relay output is activated. If the monitored temperature falls below the low set point, a SPST relay output is activated. Unit includes a 0-99 minute delay timer.

This model has been discontinued. Please use the EnviroAlert EA200 as a replacement.
