The Grant GD120 is a digitally controlled stirred water bath and circulator ideal for laboratory use, offering high precision and flexibility. Here's a breakdown of its features and capabilities:

Key Features

Immersion Thermostat with Intelligent Control Optimisation (ICO): Enables adaptive PID control for exceptionally stable temperature regulation.

Integral Pump: Built-in circulation pump with a maximum flow rate of 17 L/min, allowing both sample immersion and external fluid circulation.

User Interface: Equipped with a clear digital display, a rotor plus two-key control, timer function for reaction timing, and visual + audible alarms to notify operators of critical conditions.

Preset Temperature Control: Supports one adjustable operating setpoint plus three preset temperature options for fast switching.

Safety Features: Includes float-switch low liquid protection and an adjustable over-temperature cut-out for sample and user safety.

Liquid Type Selection: Automatically adjusts heater power and temperature parameters depending on chosen liquid (e.g., water, oil, glycol mixtures).

Temperature Range & Accuracy

Plastic Tanks (P-series): From around ambient +5 °C up to ~99 °C.

Stainless Steel Tanks (S-series): From –15 °C up to ~120 °C.

High Stability: ±0.02 °C for stable temperature control.

Technical Specifications & Obsolescence

The GD120 series includes multiple tank sizes: plastic tanks (P5, P12, P18) and stainless steel tanks (S5, S12, S18, S26, S38), offering varied capacities for different lab needs.
