Stirring hot plates resist corrosion

The EchoTherm Model HS70 Programmable Stirring Hot Plates are designed to be purged using an inert gas through a fitting on the rear of the chassis. 

Purging provides a positive pressure inside the unit to prevent corrosive gasses from entering the chassis and attacking the electronics or stirring mechanism.

These units feature 10-program memory with 10 steps per program, temperature ramping, RS232 I/O port, membrane keyboard, and full function liquid crystal display where all parameters are continuously visible. 

Heater tops are 8” square solid ceramic with 600 watts of power.  Temperatures can be set to 450°C. The units are readable and settable to 1°C.  Accuracy is 1% over the entire temperature range.

Temperature control is by PID software and is controlled to ±1°C or ±1ºF.  Stirrer speeds can be set from 100 to 1500 rpm.  Temperature ramping can be set from 1ºC/hour to 450ºC/hour in 1ºC increments. 

The built-in timer is settable to 99 hours and is readable to 1 second.

It has an audible alarm with user settable auto-off for turning off the heater and stirrer when the timer counts down to zero.  The units are supplied with a 6” Teflon immersion probe for controlling solution temperatures directly.

All units are available in 100, 115, and 230 VAC, 50/60 Hz models.
