User friendly, the Wika Mensor CTB9100-225 is a micro temperature calibration bath that functions with a temperature-controlled liquid tank with a practical working range of Ø 60 x 150 mm (2.36 x 5.91 in) depth. The CTB9100-225 covers a temperature range from 40 ... 225 °C (104 ... 437 °F), optionally 255 °C (491 °F). Need multiple sensors calibrated simultaneously? The Wika Mensor CTB9100-225 can handle that, making it the perfect solution for field temperature. Have an odd or short sensor? No problem, the CTB9100 accommodates a variety of different sensor sizes without the hassle of hauling around multiple metal inserts. Calibration work taking too long? The ambient to 50°C is typically 30 minutes so you can get your calibration work done rapidly. The bath boasts a high accuracy of 0.3 °K and a bath stability of 0.05°K while the internal memory can be programmed for as many as 4 quick set points making routine test points available with one touch. The bath comes equipped with a screw on lid keeping the bath fluid snug and in place during travel or transport. The optional magnetic stirrer ensures the bath stability is constant and provides the user with adjustable speed control. The bath uses common silicone oil which is available as an option, call for pricing.
