HD 2105.2 pH & Temperature Meter
HD2105.2 portable temperature and pH meter is rugged, easy to use, precise and extremely durable. pH/mv capability allows for the estimation of acidity/alkalinity thanks to the whole line of dedicated sensors or redox potentials with the appropriate ORP combined electrodes.
Calibration can be run with 1, 2 or 3 points among the thirteen available buffers setup. Temperature probes are equipped with automatic recognition unit (PT100 or PT1000) and factory calibration information. The data logged by the unit can be transferred to the PC via RS232C or USB 2.0 interfaces with ease of setting of storing interval, printing and baud rate. The instrument is fully IP67 protected.
