Product Overview
The TH7300 is designed to satisfy applications that demand a wider operating temperature range and is capable of controlling down to -30C with suitable cooling and up to +150C in a suitable medium. The high-flow pump ensures excellent temperature uniformity, whilst the simple to use full digital PID control system produces accurate and stable temperatures. The low watts-density element is suitable for heating silicon oil and ethylene glycol based heating media.

All Ratek immersion heater circulators are built to withstand the toughest of operating environments and feature a unique vent system to ensure steam is kept away from the control unit. The TH7300 features Rateks unique expandable clamp bracket system allowing it to be easily fitted to most brands of bath, and also includes a retort stand mounting option for applications where the circulator needs to be suspended over the tank. When used with a Ratek insulated bath, a matching bridge plate is ideal and maximises usable bath space. The TH7300 immersion circulator delivers fantastic performance and usability for more specialist use, whilst being equally suited to less demanding applications. This makes it a good all-round choice for a versatile circulator that can be moved easily from task to task.
