Features:

1.In site original sample, plug then test, no sample processing, data can be read in seconds

2.The system allows the establishment of 8 calibration tables to adapt to the testing of up to 8 different oil samples to overcome the effects of salinity;

3.Repeatability 0-30% range: 0-70% range: <0.1% abs; 70-100% <1.0%;

4.The instantaneous test value can be locked and displayed with key for easy observation

5.Test values can be stored, each calibration table corresponds to a storage function that allows recording 24 data

6.Can read and delete test records

7.The system has a backlight, which can be turned on in a dark environment

The HZWS-S2 is made using the principle that high-frequency electromagnetic waves are absorbed when passing through a substance to produce energy attenuation. Since the ratio of the absorption coefficient of moisture to microwaves to the absorption coefficient of oils to microwaves reaches 75: 1, when a high-frequency electric field is applied to oils, the presence of water will affect the phase and amplitude of the high-frequency electric field and the degree of impact Related to moisture content.

Similar technologies have been used throughout the world for many years, but the specific test methods vary from house to house. The most typical new methods are TDR and Phase dynamic. HZWS-S2 adopts the wonderful technology that Chinese scientists have explored for many years. In the application of petroleum moisture detection, it has obtained the highest repeatability, which greatly overcomes the effects of oil differences and salinity. It is the unique moisture testing technology in the world today.

Usage:

This instrument is suitable for daily moisture analysis of oil field production units, on-site analysis of crude oil moisture in oil refineries, oil-burning users' acceptance of heavy oil, on-site analysis of engine oil moisture, and rapid testing of oil and organic compounds in other occasions.

How to use:

During normal testing, just insert the sensor into the sample, turn on the power switch, and the test value is displayed on the LCD screen.

1.A simple test of only one oil sample: No matter on site or in the laboratory, first mix the oil and water evenly, then insert the sensor, and then turn on the power switch in the upper left corner of the instrument. After a few seconds, the display will show the test results. Turn off the power after reading. It takes about 10 seconds

2.Multi-table classification test users: Turn on the instrument, first observe whether the "C #" label in the upper right corner is the calibration table of the oil type you want to test, replace the calibration table of the oil product you want to test with the current calibration table, and then do the above test. 3.It also has the functions such as the recording, averaging, printing and others.

Preparation before use:

The first time you use it, you should first check whether the test data is accurate. If it is not accurate enough, you must re-calibrate with user samples.

Before leaving the factory, the instrument should be calibrated according to the same oil sample as possible. However, due to the difference between the sample and the standard method, sometimes it may not be completely consistent with the user's on-site testing. But through the user re-calibration, all can reach the technical indicators.

Instrument maintenance:

The instrument is equipped with a rechargeable battery. Each charge is about 3-5 hours, and can be used continuously for 6-10 hours. 3 days standby time. When the battery voltage is insufficient, the instrument will intermittently emit a "beep" sound, and at the same time prompt an alarm on the display.

After the instrument is used from the first time, it needs to be recalibrated after 1-3 months, and then calibrated once every six months and one year.
