Shock-resistant

Polycarbonate resin* used in automobiles and mobile phones has been adopted to enhance shock resistance.

*Polycarbonate resin has about twice the shock resistance of conventional ABS resin.

Visible LCD in dark places

Backlight allows reading of measured values even in the dark.

*Except D-71

Waterproof and dustproof

IP67 rated waterproof and
dustproof casing.

*IP67: Fully waterproof for approximately
30 minutes in 1 meter of water.

Extended operation

Uses about 10% of the power compared to conventional meters. With up to 1000 hrs of use*, long periods of field work is possible.

*D-71/D-72

Easy to carry

The compact and ergonomic design is easy to carry and includes a cable winding function with the optional electrode hook attachment.

One hand operation

Slim body fits in your hand. Only three basic operation buttons for one-hand operability.

 

Laboratory use capability

The optional electrode stand offers excellent manoeuvrability, allowing the electrode to be moved up and down, and from left to right, easily with one hand.

Easy-to-view large display shows two
measurement values simultaneously

The measurement values are easily visible on a display that is about 40% larger than those of our conventional products. Two measurement values can be displayed on a single screen.

*For selected models, an optional cable is necessary to connect to a computer.
The software can be downloaded after user registration.

Various data processing

The built-in data memory can store 1000 items, and connecting to a computer allows measurement data to be collected. Output to a GLP/GMP-compatible printer is also possible.

*For selected models, an optional cable is necessary to connect to a computer. The software can be downloaded after user registration.

Chemical resistance

The polycarbonate resin casing is extremely chemical resistant. It can be cleaned using alcohol.

*Resistant to alcohol, weak acid, bases and oil.
