1. Heating furnace structure: The heating furnace includes a heating element, embedded heating plates, and platinum resistance sensors; The middle empty slot is the sample chamber, used to place the sample assembly: including the grease cup clamp, the grease cup for loading the sample, and the lower grease cup slit. There is a light source below the heating element, which emits light through the slit hole of the slit sleeve and shines on the signal sensor. When the sample softens and drips, blocking the light hole, the signal sensor emits a signal and the instrument records the temperature.

2. Sample assembly: with a lipid cup in the middle, used for placing samples; Above is the clamp, used to clamp the upper end of the grease cup and connect the handle; Below is a slit sleeve used to pass light and catch the dripping sample when it reaches the drip point.

3. Inspection of the combination slit sleeve: Enter the main interface, click the "Test" button, set the preset temperature to no more than 40 degrees, click the "Auto Detection" button, and enter the auto testing interface.

4. The sample assembly of the empty fat cup is vertically placed in the sample chamber of the furnace, with the observation port at the lower part of the slit sleeve parallel to the front, and the transparent holes of the furnace body and the slit sleeve parallel to each other, ensuring that the detection hole can be transparent.

Portable pollution index automatic detector Automatic portableSDIceremony Model:HAD-SDIZ

1 general want

Monitoring the pollution trend of RO (reverse osmosis) system inlet water has always been an essential task. Usually, people only realize the existence of pollution problems when RO membranes need to be cleaned, but this has already caused serious downtime events and the serious consequence is the need to replace expensive membranes.

Several methods have been adopted in industry to measure the pollution trend of incoming water, such as turbidity, particle count, and pollution index (SDI) measurement. Due to the optical principle used in turbidity and particle counting measurements, non photosensitive colloids and particles cannot be detectedTherefore, it is not possible to directly measure the pollution caused by particles in the suspension, that is, the impact on the membraneThe siltation energy 力”It is very difficult to use them to judge pollution trends.

The SDI monitoring method directly measures pollution trends. ASTM D4189 specifies that the SDI measurement method measures the flow of a certain volume of water sample under a certain pressure and standard interval timeThrough microporous filterBlocking rate of 0.45 μ m.

Usually, RO (reverse osmosis) systems are used for SDI of imported raw waterValue less thanIn the case of 1

Operating for several years without any problems; If in the raw water SDIValue less thanIf operated under three circumstances, it will take several months

No need to clean the film. However, in the raw water SDIvalueSystems that operate 3-5 times require frequent cleaning of the membrane, as such systems typically do not function properly. SDIValue greater than5 raw water,

work

It cannot be used for RO inlet water at all. Therefore, accurately and timelymonitoringROWater ingressSDI is very necessary.

However, manual SDI measurement is a tedious and time-consuming task.

The EQSDI pollution index automatic measuring instrument can automatically and continuously monitor

The pollution index of RO inlet water. Operators can quickly and accurately detect reverse osmosis pretreatmentThe effectiveness of the system, therebySDIPollution index detection is no longer cumbersome and greatly reducedThe error of manual monitoring.

EQSDI uses the standard testing method described in ASTM D4189Law, to every5. Calculate SDI at intervals of 10 and 15 minutes. For well water, filtered water, and clarified lowturbidity(<1.0NTU) water can also be accurately measured.

The calculation formula for EQSDI is as follows:

SDIn=(1-to/tn)×100/n
