Colorimeter HACH DR 900
Portable colorimeter DR 900 Made specifically for work in the field. The colorimeter is resistant to dust and moisture, and can withstand shocks and falls. The HACH DR 900 colorimeter has a simple and intuitive interface, is equipped with memory and a USB port for transferring results to a computer. The device’s memory contains 90 programs for measuring the basic characteristics of water. Any program is available in just 4 button presses. Main features: LCD display with backlight; radiation source - LEDs; detector - silicon photodiode; measurements in units of concentration, absorption and percentage of absorption (the units of measurement and the measured parameter are simultaneously reflected); memory for 500 field measurement results (date and time of measurements, parameter, program number, sample code and operator code, serial number of the device); recalculation of results into various chemical forms; background value setting and standard calibration setting; the software allows you to select an analysis program by pressing a button, automatically set the wavelength and start the timer; transfer of results via mini-USB; Autonomous power supply from 4 AA elements.
