H.E.S.T. 8420 & 8420A
15ºC – 20ºC PER MINUTE LINEAR
THE GOAL: ZERO DEFECTS
Linear ramp rates, high volume and air velocity are critical to effective testing.
THE REALITY: LATENT DEFECTS
Our model 8420 Strife Testing System may be your most cost-effective solution for detecting and eliminating latent defects saving you and your customer time, and saving you huge sums.
THE SOLUTION: HARRIS
The 8420 powerhouse delivers maximum results. A 9000 CFM air circulator with velocities in excess of 100 LFM over product and ramp rates of 15ºC to 20ºC per minute, linear
Our Systems are designed to meet your requirements for quick and efficient and reliable stress testing. Our unique high volume airflow design guarantees optimum thermal stress at high and low temperatures. Cooling and heating ramp rates can be clearly configured to allow maximum stress for even hard to test devices. Modulating refrigeration valve with time proportioning solid-state relays utilizing state of the art programmable microprocessor controls to produce optimum temperature equilibrium at any point in the specified temperature range.
