Profile: Hillcrest Engineering Instrumentation Ltd. is a manufacturer of electronic temperature & pressure sensing & control equipment, wiring, and cabling products. Our product line includes temperature sensors, cable & ancillaries and switch equipment. Our HEI 0700 dry block calibrator is a versatile, robust and accurate machine designed for the use in harsh environments. The calibrator has a number of built in safety features with a unit which is able to operate at elevated temperatures of up to 600°C. The instrument can be rapidly cooled to a safe temperature for transportation. Our HCD800M manifold systems are manufactured to suit any diesel engine. The system enables a rapid change of any transducer minimizing the 'down' times resulting from failures. Our 2033 coolant performance monitor provides visual indication of coolant condition and more importantly a retransmitted signal for alarm & derate purposes. The unit is not flow or pressure dependent, and has the facility to allow the customer to determine the acceptable coolant condition by a simple manual and visual trim settings.
