KERA Technologies Inc. designs and manufactures wide variety of Time Control and Temperature Control products.
We specialize in digital, microprocessor based products for the control and monitoring of the real time and real temperature applications. This includes digital clocks and digital timers with multiple communication configurations that can be used stand alone as well as in the Master Slave Clock networks and Multizone Clock setups. Our LED Clock products are equipped with remote control units.
The large, Jumbo LED Clock models can be used as Hospital Clock, School Clock, Military Clock, Airport Clock, Marine clock, Ship clock, Submarine clock and in manufacturing plants or office installations. The digital clocks include many internal options that can be utilized in special applications like: Digital Stopwatch, Count Up Timer or Count Down Timer, Cycling timer without or with Alarm Buzzer or Siren. Our clocks can be also used as Multi Event Programmable Timers and Multi Event Programmable Thermostats in Heating and HVAC - Air Conditioning applications. Similarly, the LED clock can be setup as a Programmable Counter.
The temperature control products are Digital Thermostat and Digital Thermometer models without or with alarm and Programmable Thermostat with Timer in one unit. They are used in applications like Sauna Control, Sauna Timer, Hot Tub Control, Spa Thermostat, Steam Bath Controller as well as other Heating Control or Cooling Control installations. Other models like Programmable Water Tank Thermostat and Heating and A/C Thermostat ( HVAC Thermostat ) are available for Gas or ELectric Water Heating Control and Space Heating Control.
Special type of thermostat called Differential Thermostat is used in Solar Heating including the Solar Water Heating control. They can control the systems operating in the Solar Water Heaters with either Solar Collector Tubes or Flat Solar Collector Panels and Heat Exchangers within or outside the Water Tank by driving the Circulating Pumps and Valves.

We can customize the existing products to specific requirements from our clients and produce special models not only at Large Volume orders but also Small Quantities.
OEM designs are often feasible at a very low cost of development.
