Online CHWJ - 1302 type water sampler批发

A. The instrument function description
CHWJ - 1302 online water sampler under the control of the intelligent controller, the metering pump will water into the instrument, through sampling distribution system will be water samples sent to the specified sampling bottles, samples collected water samples by constant temperature system of constant temperature preservation, to accomplish the automatic acquisition, automatic distribution of water and constant temperature preservation process. After remit ring of science and technology of the 20 many kinds of monitoring instrument online of in-depth study, which can realize to work together with all kinds of monitoring equipment, on-line function makes the sampler and monitor can play a greater role.

The sampling apparatus has a standard sample, sampling, synchronous sampling, sampling, the hour flow ratio, the seven main functions such as remote control, sampling immediately, can fully meet customer demand for sampling, sample.
CHWJ - 1302 online water sampler, also have the power to protect, electricity saving, water protection, open closed records and various protective functions, is an intelligent automatic water quality sampling instrument.

Ii. The instrument main characteristics
(1) the instrument adopts anticorrosion, high strength material manufacturing, refrigeration thermostatic system entrust a specialized refrigerator manufacturers custom.
(2) sampling mode: standard sample, sampling, synchronous sampling, sampling, the hour flow ratio, remote control, sampling immediately.
(3) the sample temperature preservation function: under control in temperature control system, which can realize the sample temperature preservation.

(4) history query function: historical records retention samples including sample number, date of sample, sampling mode, sample quantity and bottles of information, can store up to 5000 sampling record. Historical records including power power blackout dates, time and state information. History open record is including open closed date, opening, closing time, close the information such as the status and action.
(5) communication function: standard communication interface, can be through the RS 232, 4-20 ma, and other forms of interface with a variety of monitoring instrument online of communication.
(6) open closed records: water samples of freezer door switch state can be detected, and record every time open the closing time.

(7) power protection function: when the accident and again on the electric power, the sampling instrument to restore to the power working condition, set the parameters of the same, and can continue to complete the follow-up samples.
(8) external pump control function: when the sampling distance is greater than the built-in sampling pump working distance range, external sampling pump relay sampling can be produced.
