UNSTIRRED DIGITAL
WATER BATH
CAT NO. WBTH-6H
Instruction Manual

SUMMARY
Water Bath is used for distillation, concentration, drying and thermostatic
heating in schools and colleges.
1. The enclosure of the product is formed and machined by using high-
quality steel plate. Static electric spraying process is adopted on the
surface, which is sturdy and durable. The inner container is finished
by the stainless steel stretching.
2. The liner and upper cover are made of high-quality stainless steel
plate, featuring strong corrosion resistance.
3. U-shapped heating pipe is used for direct heating in water. The
temperature rise is quick and the thermal loss is less.
4. Single-row digital display or intelligent temperature controller boasts
simple operation and favorable application effect.

OPERATION
1. Put the instrument horizontally.
2. Open the cover and add distilled water to the water tank. The water
level must be higher than the heating pipe and temperature sensor.
3. Connect the suitable power & switch ON the power switch.
4. The upper row of the instrument shows test temperature and setting
temperature is showed in the lower row.
5. Shot pressing the setting key can enter the setting state. Shift, plus
and minus keys can adjust the temperature.
6. Press the upper key to set time, when the upper row shows ST and
the lower row shows OFF, press the upper key again then the lower
row shows the time. The shift key is used to change the numerical
which unit is minute. There are two kinds of timing modes which are
timing after temperature constant and timing after setting finished.
When the time arrived, heating output stopped. To start the
operation again, the power switch must be shut OFF and ON again.
7. Automatic tuning function: if the test temperature fluctuates, the self-
tuning function can adjust. Press the plus & minus key till the
indicator light on.
