Key Features
Wireless 4-Channel Multi Connection
By using wireless adapters (Bluetooth, commercialized product), the operation unit and the titration unit can be used together without being connected to each other with a cable. You can carry out titration of a sample, which emits poisonous gas, safely by keeping the titration unit inside a draft chamber while keeping the operation unit outside of it. You may place the operation unit on the opposite side of aisle or hold it with your hand by connecting a battery (commercialized product) to it for operation. Attaching a monitor arm to the main control unit allows for flexibility of its mounting position. The arm mount of the display is compliant with VESA standard 75mm × 75mm.
Wireless connection between operation unit, touch panel, and titration unit enables simultaneous measurement with up to 4 titration units.
New-Type Burette Unit
The burette unit has the switching valve on top of the cylinder. The structure reduces dead space in the tube between the cylinder and the switching valve. In addition to the reduction of dead space in the cylinder, the structure reduces amount of residual titrant to ease replacement of titrant.
Maximum Electrolysis Speed
Unique technology enables maximum electrolysis speed of 2.6mgH₂O/min. It reduces pre-titration time and measurement time.
Smooth Operation with Touch Panel
Models feature intuitive touch panel control for easy operation.
