Silica Photometer Water Resistant with CAL CHECK

Silica Photometer Water Resistant with CAL CHECK

This meter measures the molybdate reactive silica content in water samples in the 0 to 200 mg/L (ppm) range. The method used is an adaptation of the USEPA METHOD 370.1 for drinking, surface and saline waters, domestic as well as industrial washes and Standard Method 4500-SiO2 C.

This instrument contains the powerful CAL CHECK validation function which allows you to validate your performance at any time. This whole system is user friendly and with the NIST traceable standards you will be able to verify the performance of the instrument and recalibrate if necessary.

This unit has an advanced optical system based on an LED (Light Emitting Diode) and a narrow band interference filter that allows the most accurate and repeatable readings.

This meter is water resistant and the lamp and filter are protected by a transparent cup, making it ideal for field work. This meter also features an auto-shut off feature that will turn off the instrument after 10 minutes of non-use in measurement mode and after 1 hour of non-use in calibration mode. This meter also has a positive locking system to ensure the cuvets are oriented in exactly the same way each time you test. The meter also allows for cuvets with larger necks to ease the process of adding both reagents and samples.

This meter comes with 2 sample cuvets with caps, a 9V battery and an instruction manual.
