Controlled by microcomputer, large LCD: working status of
instrument, operating procedure and testprogress
Steam transmitter High/middle/low/empty water levels, steam
pressure, temperature.
Monitoring the condensing tube temperature, in case the temperature
is over 40℃, the alarm will be on.
Middle, low, empty and high liquid levels of water, boric acid,
sodium hydroxide, the alarm will be on when liquid level runs
empty.
he alarm will set off when waste liquid level is full
One key touch sets work procedure of the instrument:
User can set steam pressure and temperature of operation and
standby mode, when the instrument is at standby mode, stop
supplying water is counted into water collecting time (for the
purpose of water savingconfigurations)
Touch pad, upon pressed touch pad, the certain quantity of water will
automatically come in, together with boric acid and sodium
hydroxide (Precision: ml, accuracy±1.5%, subject to water)
One key touchmicrocomputer will automatically suggest fill up over 50% sodium
hydroxide according to the residuals in the digestive tube.
One key touch: sodium hydroxide can be added in several times, and renew steam.
The pressure and temperature of instrument on operating and standby
modes, together with theduration of stop water supplying from
standby to rest (for the purpose of water saving, optional),
recovery rate is more than 99%.
One key touch: It’s allowed to activate alarm by pressing one key only while setting response time, distillation time, and waste
liquid siphoning time, in addition, it may print operation
materials, (the operation procedure may be finished by just
pressing one key), recovery rate is more than 99%.
Power 2200W
distillation speed 30-40ml/ min
Principal part of shell is made of stainless steel
The key parts are covered by ABS plastic for protection, and
resistance to hot alkali

240128 Lattice big LCD with optional display of Chinese or English.
. Real-time display unit status, operation procedure, test
progress, liquid level and temperature
Display unit status: steam transmitter has liquid level / pressure
/ temperature. The temperature of condenser tube, and various
liquid levels.
Operation procedure: access to the reaction standby section after
filling up all the reagents in order, then distill, and alarm is
over; waste liquidsiphoning, finish the alarm; standby stage.
Test progress: the reaction time after adding NaOH; time remaining
of distillation upon starting; waste liquid siphoning time
aftersiphoning.
Accessing to dormant state after stop working for 10 minutes (steam
transmitter temperature is less than 80 ℃), with very fast speed in
restart
Applying Snake-like stainless heating pipes, which features fast
heating speed and long life span. The heating power: 2100W above.
Steam transmitter pressure could be set, 30－40mL/min condensing reclaimed liquid
Built-in microcomputer, operator can set according to the demands:
Steam pressure: it had been set when leaving factory, generally, no
necessary to alter it; with automatic protection to overpressure.
Steam temperature: within 130℃, modify according to measured
requirement.
Residual volume of vitriol oil: 9999.9mL(the previous one is
maximum setup, self configuration is permitted on demand), the
computer will advice to add amount of NaOH exceeding 50% of the
volume.
Automatic added volume of NaOH: 9999.9mL, the times of adding could
be set. (The previous one is maximum setup, self configuration is
permitted on demand)
Response time: 99 minutes and 59 seconds, kjeldahl nitrogen determination could be o” for certain seconds. (the previous one is maximum setup, self configuration is
permitted on demand), the function is primarily used for organic
chemistry reaction like measurement of acidum citricum.
Distillation time: 99 minutes and 59 seconds, in common cases, in
2-5 minutes, (the previous one is maximum setup, self configuration
is permitted on demand)
Reclaimed liquid (pumping waste liquid) Time: 99 minutes and 59
seconds, generally, less than 50 seconds. (The previous one is
maximum setup, self configuration is permitted on demand)
Imported built-in electronic diaphragm pump, designed for supplying water to steam transmitter.
Imported built-in metering pump siphons NaOH, water, and H3BO3
(error of water metering is less than 1.5%)
Built-in anti-corrosion pump will siphon waste liquid, and drain it away
independently. Waste liquid could be ef
