Main functions

It is used to measure the osmotic pressure of plant tissue. The instrument is simple to operate, has a single-key automatic calibration function and an alarm function, and also has statistical functions, which can display the average or standard deviation values ​​of several samples.

Main features

1. Accurate

The error rate of VAPRO osmometer is <1%;

After 30 years of clinical trials, it has been proved that VAPRO osmotic pressure instruments are far superior to other similar measuring equipment.

2. Quick

In just two steps, the accurate volume of friction can be measured in 75 seconds.l concentration.

3. Easy to operate

Automatic control of all measurement processes;

Built-in automatic comparison function;

Automatically prompt the operation process;

No special maintenance is required;

The experimenter no longer needs to undergo complicated training to obtain accurate results.

4. Economical and durable

Just a VAPRO osmotic meter, no need to purchase any accessories or reagents to complete the measurement, and it is durable.

5. Self-detection

Built-in self-test function, check it as soon as you turn on the computer.It can display temperature conditions, water quality in the cleaning bottle and other conditions that affect the accuracy of data. It can also detect the performance of each component of the instrument. At the same time, standard deviations are used to assist users in judging the repetition of data during the measurement process, and can remind users to operate.Error or step error.

6. Statistics and calculation functions

The mean and standard deviations of multiple samples can be recorded and displayed.

7. Save operating costs

Except for the standard calibration fluid, other consumables do not need to rely on manufacturers or distributors.

8. Automatic cleaning

Equipped with deionized water bottles and waste liquid bottles, automatic cleaning of thermocouple heads can reduce maintenance steps and improve instrument performance.

9. Data storage and output

It can store up to 16 records, and the RS-232 and USB interfaces can be directly connected to the computer and printed, making it convenient for data output.

10. Menu Driver

Streamlined user interfaces can quickly access menu options and common functions;

User-selected measurement mode: single sample measurement, automatic repeat mode can measure the same sample multiple times, average mode can obtain more accurate data, and start delay mode is designed for samples that require longer equilibrium time;

Four languages ​​are available: English, French, German and Spanish.
