CT-1000HT Series Constant Temperature Bath
The CT-1000HT Extended Range Constant Temperature Bath is designed for precise kinematic viscosity testing in compliance with ASTM D445/D446 and ISO 3104/3105 standards. It offers a wide temperature range from 25 °C to 200 °C with high accuracy. Featuring a motor-driven stirrer for uniform bath temperature, the CT-1000HT ensures safe operation with overtemperature and low liquid level sensors. Its user-friendly design accommodates up to seven simultaneous viscosity determinations. Ideal for oil and fuel testing, it also provides efficient temperature control with two electric heating elements and a stainless steel cooling coil for flexibility in temperature management.
Test temperatures < 40 °C and high ambient temperature test environments require an optional bath cooler

Features & Benefits
Precise and accurate temperature control
- Temperature range: 25 °C to 200 °C
- Temperature accuracy: ± 0.01 °C from 25 °C to 100 °C; ± 0.03 °C from 100 °C to 200 °C
- Temperature selection is variable between 25 °C and 200 °C or selectable at ten pre-set temperatures (25 °C,40 °C, 60° C, 80 °C, 100 °C, 135 °C, 150 °C, 165 °C, 185 °C, and 200 °C)
- Meets ASTM D445 temperature sensitivity requirements for kinematic viscosity determination
- Motor driven stirrer ensures a uniform bath temperature
Safe operation
- Bath thermistor senses over-temperature fault and removes power
- Thermistor disconnection results in removal of bath heater power
- Liquid level sensor prevents operation if bath liquid is not at a safe operating level
Efficient, user-friendly design
- Seven glass viscometer ports (each 2” in diameter) and two thermometer ports (each 0.4” in diameter) allow up to 7 simultaneous viscosity determinations
- Two electric heating elements quickly heat bath media to the selected temperature
- Stainless steel baffle provides a plain reflective viewing background
- Integrated stainless steel cooling coil allows connection to tap or recirculating water chiller for temperatures slightly above or below ambient. An external thermoelectric bath cooler is also available.
- Convenient drawer provides easy access to electrical controls
Reliable performance
- Well tested CANNON bath platform offers reliability and dependable support
- All wetted components are manufactured from high quality stainless steel or glass
The heavy duty aluminum frame offers a corrosion-resistant epoxy finish
