　　-|[Product Features]|-

Separating the digestion instrument from the measuring instrument does not affect the measurement accuracy. Temperature PID automatic temperature control and timing.

High performance ultra-low power 16 bit microcontroller, with instrument standby time of over 6 months.

Time saving operation.

Cold light source, narrowband interference optical system, good optical stability.

Data power-off protection function.

Each can save 30 standard curves and 199 measured values (including time tagged year, month, day, hour, minute, second measured values, absorbance values, and transmittance)

Equipped with a USB port, it can be connected to a computer for recording, reading, or printing stored data.

The host chassis is made of molded ABS material, with an IP65 design and good waterproof and dustproof performance.
