Automatic Cleaning

The ISA - UV/Vis Spectrometers feature an integrated and automatically controlled pressurised air flushing for the cleaning of the optical windows. No mechanical parts protrude from the measuring head, which eases the installation in armatures and prevents the settling of dirt particles on the optical windows. With the pressurised air flushing the service expenditure can drastically be reduced.

No Consumables

The UV/Vis Spectrometers do not require any reagents or other consumables and can be operated maintenance-free except for necessary cleaning on location (dependent on the installation). The calculated life-time of the flashbulb is > 10 years. In the case of a defect, service on location is possible because all electronic components are external to the submersible probe.

Deployable up to +110 °C

The ISA measuring head features an extremely high-temperature durability of +80 °C (for short periods, up to +110 °C). This substantially extends the range of applications, particularly for industrial implementations. The temperature insensitivity of the ISA is an advantage for cleaning and sterilization of the probe head. Since there are no electronic components in the measuring head, temperature influences (drift) on the electronics, UV/Vis lamp, and Spectrometer unit are eliminated.

ATEX Certified

The measurement head of the ISA - UV/Vis Spectrometer system is ATEX certified, which allows for the installation in potentially explosive atmospheres. The measurement head fulfils ATEX class III as standard. Optionally, ATEX class II is available.

Adjustable Optical Path Length

The measurement head of the ISA - UV/Vis Spectrometer allows for an infinitely variable adjustment of the optical path length between 0.5 to 20 mm, which is a unique feature of the ISA Spectrometer. The path lengths can be changed directly in the field by using a simple screwdriver. The adjustment of the measuring path is an imperatively necessary feature for optimal adaptation to the local specific water matrix. In addition, the possibility of opening the measuring gap eases the ability to perform a manual cleaning.
