Features

• Membrane-covered galvanic dissolved oxygen sensors to measure in water and aqueous solutions - low-maintenance and no polarization time required
• For instant measurement
• Easy air calibration with water vapor saturated air in the calibration vessel
• User friendly and long operation time

CellOx^® 325 – proven and tested oxygen sensor with build-in temperature probe from German WTW is easier to use and offers more quality and precision.

Features

• High spatial resolution (<50 μm)
• No self-consumption of oxygen
• Penetration probe for insertion into vessels, sediments or biofilms
• Penetration through septa or skin
• Easy to handle
• Different needle sizes and lengths available
• Signal independent of flow velocity
• No time for polarization necessary
• Insensitive towards electrical interferences and magnetic fields
• Measures oxygen in both liquids and the gas phase
• Optimal measuring range from 0 to 50 % oxygen (0-22.6 mg/L)
• Maximum measuring range from 0 to 100 % oxygen
• Limit of detection 0.2 % air sat., 20 μmol/L
• Sterilizable (H₂O₂, EtOH)

Micro oxygen sensors designed for all research applications were a small tip size and a fast response time (<3 sec) is necessary.

Needle-type oxygen microsensors are ideal for animal physiology and for oxygen distribution profiling in sediments or biofilms with micro-manipulators for high spatial resolution. The oxygen-sensitive tip of an optical fiber is protected inside a stainless-steel needle. This design allows for easy penetration through a rubber septum or any other harsh material as well as for transportation.

Features

• High spatial resolution
• High temporal resolution
• High flexibility
• Bare tip – no housing
• Sterilizable (autoclave (130 °C, 1.5 atm), EtOH, EtO, H₂O₂)
• Measuring range from 0 to 250 % air sat. (0-22.6 mg/L)
• Limit of detection 0.2 % air sat., 20 µmol/L
• Small outer dimensions
• No consumption of oxygen
• Signal independent of flow velocity
• No time for polarization necessary
• Insensitive towards electrical interferences and magnetic fields
• Measures oxygen in both liquids and gas phase

Micro oxygen sensors designed for all research applications were a small tip size and a fast response time (<3 sec) is necessary.

Implantable oxygen microsensors are miniaturized fiber-optic sensors that has no housing so you can mount/insert it through canulae, catheters, syringe needles etc. for in-vivo measurements in the blood circuit of living animals or liquid circuits of trees.

Replacement temperature probe for Witrox 1 and Witrox 4 instruments with a 5 m long shielded cable. The Pt1000 sensor has a tolerance of 1/3 of Class B sensor giving a very high accuracy of +/- 0.15°C.
