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.
Backlight allows reading of measured values even in the dark.
*Except D-71
IP67 rated waterproof and
dustproof casing.
*IP67: Fully waterproof for approximately
30 minutes in 1 meter of water.
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
The compact and ergonomic design is easy to carry and includes a cable winding function with the optional electrode hook attachment.
Slim body fits in your hand. Only three basic operation buttons for one-hand operability.
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.
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.
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.
The polycarbonate resin casing is extremely chemical resistant. It can be cleaned using alcohol.
*Resistant to alcohol, weak acid, bases and oil.
