Temperature Sensor PT1000 230mm | Globe Scientific GHS-S230 Hotplate Probe

The temperature sensor GHS-S230 from Globe Scientific is a 230mm PT1000 probe designed for use with GHS-series hotplates and hotplate stirrers. This sensor enables closed-loop temperature control by measuring directly inside the vessel, providing accuracy within ±0.5°C on GHS-380 models and ±0.2°C on GHS-550 models.

Temperature Sensor GHS-S230 Features

The 230mm stainless steel probe reaches into standard laboratory flasks and beakers for direct sample temperature measurement. PT1000 resistance technology delivers stable, drift-free readings across the operating range of the connected hotplate.

Compatible with all Globe Scientific GHS hotplate models that include heating capability. Pair with a retort stand (GHS-STD for 550 series or GHS-STDSM for 380 series) for secure positioning above the plate surface.

Technical Specifications

Temperature Sensor Applications

Laboratories performing temperature-critical reactions use external sensors for direct vessel measurement rather than relying on plate surface readings. This closed-loop feedback prevents overshoot and maintains target temperatures precisely during extended experiments.

Analytical and pharmaceutical labs depend on PT1000 probes for documented temperature accuracy in validated methods. The GHS-S230 sensor is an essential accessory for any protocol requiring traceable temperature control.

Why Choose Globe Scientific Accessories

Globe Scientific temperature sensors and stands are purpose-built for the GHS hotplate platform. PT1000 resistance elements deliver stable, drift-free measurements that maintain calibration accuracy over extended use. Each sensor is tested for electrical continuity and thermal response before packaging.

Using matched accessories from the same manufacturer eliminates compatibility issues that arise with third-party probes. The GHS sensor plugs directly into the hotplate connector without adapters, simplifying setup and reducing potential points of failure in the measurement chain.

Frequently Asked Questions

What is the difference between the GHS-S230 and GHS-S230G sensors?

The GHS-S230 has a standard stainless steel probe. The GHS-S230G adds a glass coating for use with corrosive solutions, acids, or media that would attack bare metal. Both are 230mm PT1000 sensors compatible with all GHS hotplate models.

Do I need a retort stand with the temperature sensor?

A retort stand and clamp (GHS-STD for 550 series, GHS-STDSM for 380 series) securely positions the probe above the hotplate surface and inside your vessel. The stand is sold separately from the sensor.

Which Globe Scientific hotplates work with this sensor?

All GHS-380 and GHS-550 models with heating capability accept the GHS-S230 sensor. Stirrer-only models (GHS-380S, GHS-550S) do not have heating and therefore do not use temperature sensors.
