HORIBA D71 Portable pH and Temperature Meter

HORIBA D71 Portable pH and Temperature Meter were designed for precision water quality testing. There is 5 different meters available in the series with varying sensors ranging from the simple D-71 for measuring pH and temp to the D-73 that measures a huge range of elements such as Nitrogen, Potassium and Calcium with the optional ISE sensors.

Available meters are :

D-71 Economical meter for pH and temperature.
D-72 Multi-parameter for pH/temperature/ORP with PC/printer output capability.
D-73 Multi-parameter for pH/temperature/ORP/ISE with PC/printer output capability.
D-74 Multi-parameter for pH/temperature/ORP/conductivity with PC/printer output capability.
D-75 Multi-parameter for pH/temperature/ORP/dissolved oxygen with PC/printer output capability.

Each instrument kit includes: Meter, soft case, batteries and instruction manual. Electrodes are ordered separately.

Cutting Edge Sensor Technology
At the heart of every D-70 series meter is a number of innovative sensors that carry on Horiba’s over 60 year tradition of sophisticated sensor design and technology.Temperature: Every Horiba water quality analyzer comes with a powerful temperature sensor, capable of delivering readings quickly at a range between 0 and 100°C with a resolution of 0.1°C

pH : Horiba pH meters use a glass electrode method to deliver rapid response times and accuracy to 0.01 pH. Horiba pH sensors are highly responsive to electromotive force and to changes in alkalinity, have a low internal resistance and are extremely durable, making them ideal for use in both field and laboratory conditions.

ORP : Upgrading to the D-72 adds the capability to read oxidation reduction potential (ORP) via a three-in-one combination electrode sensor. Readings are possible within the range of -1999 to 1999 mV, with a resolution of 1 mV.

Conductivity : Horiba D-74 includes all the functionality of the D-72 plus an additional AC bipolar method sensor for measuring conductivity. Readings are accurate to a resolution of 0.05% FS within the following ranges .000mS/m – 19.99S/m (cell constant 100m-1), 0.0μS/m – 1.999S/m (cell constant 10m-1), 0.00mS/m – 199.9S/m (cell constant 1000m-1).

Dissolved oxygen : Use the Horiba D-75 water quality analyzer to obtain highly accurate dissolved oxygen measurements. The unit is equipped with a diaphragm galvanic battery method sensor providing readings between 0.00 ~ 19.99mg/L with a resolution of 0.01mg/L. Accurate readings can be obtained within 30 seconds. Additionally, the sensor is water proof and contains a replaceable ship-type electrode.
