Torrey Pines Scientific EchoTherm HS70 Corrosion-Resistant Fully Programmable Digital Stirring Hot Plates

Torrey Pines Scientific has announced the EchoTherm Model HS70 Corrosion-Resistant Fully Programmable Digital Stirring Hot Plates, suitable for use with aggressive chemicals in environments where other stirring hotplates would be quickly destroyed by vapours or spills. The hotplates 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 gases from entering the chassis and attacking the electronics or stirring mechanism.

The 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 20.3 cm² solid ceramic with 600 W 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.

Stirrer speeds can be set from 100 to 1500 rpm. Temperature ramping can be set from 1°C/h to 450°C/h in 1°C increments. The built-in timer is settable to 99 h and is readable to 1 s. It has an audible alarm and can automatically turn off the heater and stirrer when the timer counts down to zero. The units are supplied with a 15.2 cm teflon immersion probe for controlling solution temperatures directly.

All units are available in 100, 115, and 230 VAC, 50/60 Hz models. They are UL, CSA and CE or equivalent agency certified and available in voltages for use anywhere in the world.
