DTA-1
Digital Temp Alert (DTA-1) $ 262.95
The DTA-1 operates from 12V DC or AC, features bright LED 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. Alarm condition activates SPDT relay output.

TA-1
Mechanical Temp Alert (TA-1) $ 78.50
The economical TA-1 requires no power for operation. Simply set the separately adjustable high and low set points within -30 to +130 deg F (-34 to 54 deg C) range. If the monitored temperature rises above or falls below the set points, a dry contact closure output is provided

TA-2HL
Mechanical Temp Alert (TA-2HL) $ 93.50
The economical TA-2HL requires no power for operation. Simply set the separately adjustable high and low set points within -30 to +130 deg F (-34 to 54 deg C) range. If the monitored temperature rises above the high set point, a dry contact closure output is provided. If the monitored temperature falls below the low set point, a second dry contact closure output is provided.

TA-40
Mechanical Fixed Temp Alert (TA-40) $ 22.50
The simple low-cost TA-40 requires no power for operation. A mechanically fixed set point provides a dry contact closure output when the monitored temperature falls below the 39 deg F (4 deg C) set point. This contact output is used to active external low current/voltage alarm devises.

DTA-4
Digital TempAlert 4-zone (DTA-4) $295.00
The microprocessor-controlled DTA-4 operates on 12 to 14 VDC power, monitoring both a high and a low temperature set point in up to 4 zones. Each zone has separately adjustable high and low set points and a SPDT relay output. Relay actives upon temperature rising above the high limit or falling below the low limit set point. Required probes are available separately for measuring temperatures from -67 to +300 deg F (-55 to +149 deg C).

DPM-4
Digital Temp & Humidity Alarm, 4-zone (DPM-4) $ 295.00
The microprocessor-controlled DPM-4 operates on 12 to 14 VDC power, monitoring both a high and a low temperature set point in 2 zones and monitoring both a high and a low humidity set point in 2 zones. Each zone has separately adjustable high and low set points and a SPDT relay output. Relay actives upon temperature or humidity rising above the high limit or falling below the low limit set point. Required probes are available separately for measuring temperatures from -67 to +300 deg F (-55 to +149 deg C) and humidity of 5% to 95% RH.

HA-1
Humid-Alert (HA-1) $ 95.00
The HA-1 is a stand-alone humidity-monitoring device requiring no power for operation. Simply set the single high or low adjustable set point within 20% to 80% range. If the monitored humidity set point is met or exceeded, a SPDT micro-switch will activate.

MTA-1
Mechanical Temp Alert (MTA-1) $ 88.00
The professional looking MTA-1 requires no power for operation. Simply set the separately adjustable high and low set points within +32 to +100 Deg F (0 to 38 deg C) range. If the monitored temperature rises above the high set point, a dry contact closure output is provided. If the monitored temperature falls below the low set point, a second dry contact closure output is provided.

Monitor four zones with any combination of a remote temperature, humidity or water sensing probe.

 If temperatures and humidity deviate from the preset limits or water forms a bridge between the contacts on the Water Bug. sensor the designated relay for each zone will activate an alarm, dialer, transmitter, etc.

TA-2HLD
Digital Temp-Alert (TA-2HLD) $ 142.95
The full featured, microprocessor-controlled TA-2HLD operates from 12 or 24V DC/AC, highlights 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. 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.

TA-3HLD $ 168.95
Digital Temp-Alert w/Buzzer (TA-3HLD)
The full featured, microprocessor-controlled TA-2HLD operates from 12 or 24V DC/AC, highlights 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.
