This Pt100 temperature probe is robustly constructed with a stainless steel protection sheath, moulded mini handle with built in stress relief and complete with 3 m of shielded cable and connector for our AMP, REG and DAQ instruments.

The Pt100 temperature sensor can be connected to the OXY-1 series oxygen meters. It can be used to determine the temperature during experiments and for real-time temperature compensation of oxygen measurements.

Features

• BOBS™ compatible
• High spatial resolution (<140 µm)
• No reference electrode needed
• High temporal resolution (1-2 sec)
• Measurement range: 5.5 - 9 pH
• No reference electrode needed
• Immune to electrical and magnetic interference
• pH sensing based on average luminescence lifetime detection (patented DLR technology)

This fiber optic micro pH sensor is housed inside a 70 mm long syringe needle compatible with the sample holder for our BOBS™ instrument to allow real-time measurements of pH in micro liter samples.
The pH sensitive tip of the optical fiber is protected inside a stainless steel needle, but for measurement purposes the tip can be exposed by pressing a plunger. This design allows for easy penetration through skin, a rubber septum or any other harsh material as well as for secure transportation and insertion.

Features

• The new optimized membrane glass guarantees quick measurement even at low temperatures
• The silver ion-free reference electrolyte prevents interference by precipitated silver (self-cleaning)
• SenTix^® PLUS electrodes with Gel electrolyte and a plastic body are robust and shockproof
• The membrane glass is optimally safe-guarded by a protective shield
• SenTix^® H and HW electrodes: electrolyte flow speed can be adjusted for optimal use
• The easy to use fill-hole cover prevents electrolyte from leaking out during storage
• Waterproof DIN or BNC plugs, either as a plug head system or with fixed cables, are available
• SenTix^® PLUS electrodes with liquid electrolyte – the capillary effect of the platinum wire guarantees constant outflow and prevents contamination by precipitates or dirt even during changes in temperature; with new membrane glass for an even quicker response
• Measures also the temperature

SenTix^® 41 – proven and tested pH electrode system with build-in temperature probe from German WTW is easier to use and offers more quality and precision.
