The temperature sensor GHS-S230G from Globe Scientific features a glass-coated 230mm PT1000 probe for use with corrosive solutions and aggressive media. This acid-resistant sensor enables closed-loop temperature control on GHS-series hotplates and stirrers, protecting the probe from chemical attack while maintaining measurement accuracy.
Glass-Coated Temperature Sensor Features
The protective glass coating shields the PT1000 element from acids, bases, and organic solvents that would damage standard stainless steel probes. At 230mm length, the sensor reaches into standard laboratory vessels for direct sample temperature measurement.
Compatible with all Globe Scientific GHS hotplate models that include heating capability. The glass coating is particularly important for acid digestion, corrosive buffer preparation, and chemical synthesis involving aggressive reagents.

Glass-Coated Sensor Applications
Analytical laboratories performing acid digestions use the glass-coated sensor to monitor vessel temperature without probe corrosion. Environmental testing labs rely on it during aggressive extractions with organic solvents and concentrated acids.
Pharmaceutical and chemical research facilities benefit from the extended probe life when working with corrosive media daily. The glass coating eliminates the cost of frequent sensor replacement common with standard probes in harsh environments.
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
Why choose a glass-coated sensor over the standard GHS-S230?
The glass coating protects the PT1000 probe from acids, bases, and corrosive chemicals that damage standard stainless steel sensors. Choose the GHS-S230G if your workflow involves acid digestion, corrosive buffers, or aggressive organic solvents.
Is the glass-coated sensor fragile?
Laboratory glass coatings are designed for chemical protection and withstand normal handling during insertion and removal from vessels. Avoid dropping or striking the sensor against hard surfaces. Handle with the same care as other glass laboratory instruments.
Can I use this sensor with all Globe Scientific hotplates?
Yes. The GHS-S230G is compatible with all GHS-380 and GHS-550 hotplate and hotplate stirrer models that include heating. Pair it with a retort stand (GHS-STD or GHS-STDSM) for secure positioning.
