mTCII Temperature Controller & Heater

The mTCII micro-Temperature Controller is a versatile 2 channel temperature controller powerful enough to heat small tissue baths, microscope stages, small animal heaters etc. but also able to control miniature heating devices like the included HPRE2. The mTCII uses state-of-the-art microcontrollers to provide a flexible instrument rather than a modular PID design where there is no control over the user interface and instrument function. The mTCII has two ways of driving heaters, with a PWM (pulse width modulated 2.5-20kHz) or an analog output for lower noise. In the PWM mode it can control currents up to 1.5Amps provided by a Li-ion battery or 15V power supply. The HPRE2 Pre-heater is a 3 loop capillary heater for pre-heating solution.

Combined with the CMC C-Stim or FHD microscope chamber system, this controller and heater package offer a complete solution to properly maintaining and monitoring temperature during your experiments.
