The OZONE-IN-CLEAN-WATER SENSOR BMT 965AQ-LC is a precise UV photometer for direct measurement of the ozone content of clear and clean water, or water with constant turbidity, without gas bubbles. Clear means: very low turbidity. Clean means: very low deposits on inner surfaces. Cleaning of the quartz cuvette windows, if necessary, is quite simple. Materials in contact with the ozonated water are: stainless steel, PVDF, PFA, quartz and FFPM. Superior stability of the photometer is achieved by use of a true dual beam optical system with an extremely long-life mercury lamp. MTBF of the instrument, including the lamp, is in excess of 65,000 hours. Excluding the lamp, it is 120,000 hours. The BMT 965AQ-LC is a SENSOR because it does not have a display. It is designed to directly be connected to a workstation via a 4 - 20 mA, or 0 - 10 V signal line, or via an optional isolated RS-232 serial connection. An optional Remote Display BMT 965 RD is available for installations without a workstation. To operate with the Remote Display, the BMT 965 AQ-LC has to be ordered in the version BMT AQ-LC/RD. An eight gigabyte non-volatile log memory is included, providing virtually unlimited storage capacity for concentration and error logs. If connected to a PC, the instrument acts as an external USB drive, from which concentration and error logs can be downloaded. Logs can also be copied and firmware can be upgraded without an external computer just by connecting a USB flash drive. Complete control of all operating parameters is provided with the Windows software BMT 965 Link.
The OZONE - IN - WATER SENSOR BMT 965 AQ-LC comes in a splash proof aluminum enclosure (IP 65, NEMA4X) 360 x 160 x 91 mm (W x H x D) with sea water resistant coating (RAL 5009, azure), and weighs about 4 kg. Four mounting brackets are provided for installing the SENSOR where it is needed, e.g. underneath a work bench. All electric connectors are water proof. As long as the cuvette of the SENSOR remains clean, zeroing of the instrument is not necessary for weeks, or even for months. But for safety, zero reading should be checked on a regular basis.
