Precise Water Analysis in High Quality Design

MD 100 Photometer uses high quality interference filters with long-life LEDs as a light source withou any moving parts in a transparency sample chamber. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling. The calibration and software-based adjustment options mean that the MD 100 is also suitable for use as a testing instrument.




Scroll Memory (SM)

To avoid unnecessary scrolling for the required test method, the instrument memorizes the last method used before switching off the instrument. When the instrument is switched on again, the scroll list comes up with the last used test method first.


Zero Setting (OTZ)

For certain versions of the instrument it is not necessary to zero the instrument each time. The zero setting is held in memory until the device is turned off. The zero setting can be confirmed whenever it is required. (One Time Zero - OTZ).


Manufacturers Test Certificate M

Manufacturers test certificates M are individually supplied per instrument and per method. The manufacturers test certificate M has to be ordered together with the new instrument and cannot be delivered at a later stage.


N.I.S.T Traceability

The instrument has a factory calibration, which is related to international standards which are no N.I.S.T tracable. The instrument may be calibrated by the user in a "user calibration mode" with N.I.S.T traceable standards.


Data Transfer

The optional available IRiM (infrared interface module) uses modern infrared technology to transmit measurement data form the MD 100 photometer to one of 3 optional interface. These interfaces can be used to connect to a PC, a USB printer HP or alternatively a serial printer. Applicable for the following operating systems : Windows XP, Windows Vista and Windows 7.
