DUOYI Digital Manifold Gauge Refrigeration Pressure Tester Vacuum Temperature Meter Air Conditioning Valve Tool PK HAVC TESTO
The intelligent electronic refrigerant group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storage. The instrument has double pressure test, dual temperature test （need test clip）.Note: DY517 does not include the test clip (need to be purchased separately), DY517A contains the test clip. And digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. The instrument uses high-strength engineering plastics and flexible non-slip silicone design, the whole machine is solid and comfortable to hold. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Large-size liquid crystal display, LCD backlight support, data display clear and easy to read, convenient light operation. Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument’s durability and versatility.
The instrument can measure double pressure (gauge pressure) at the same time, as well as dual temperature measurement , with automatic multi-unit pressure conversion, automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate direct reading of operating process data. Also it tests percentage of vacuum measurement; pressure leak measurement, leak time speed record. It is deserved to have this multi-functional, accurate and simply operated digital manifold let you do the job right.

Safety rules and precautions
1) The pressure measured by the digtal manifold pressure tester is gauge pressure.
2) Pressure testing ranges from -101Kpa to 6Mpa (-0.1bar to 60bar).
3) The limit pressure is 10 Mpa (100 bar).
4) The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar ).
The limit pressure is 3000 PSI approximate 20.68 Mpa, 206.8 bar ).
5) Please confirm the rated pressure value of the tested equipment before testing.
Do not use it if it exceeds the range of the instrument. Also for DY517A, if the packed
hoses does not match the pressure requirement, you can use suitable replacements for testing.
6) Do not use and store the instrument in high temperature, high humidity, flammable, explosive and strong electromagnetic fields.
7) Please do not change the instrument internal circuit, to avoid any damage of the instrument or danger occurring.
8) Please wear qualified protective equipment to protect user during testing.
9) Please use the instrument in a well-ventilated environment to prevent inhalation of toxic gases.![]()

Everything is fine. Fully satisfied.
Excellent! Shortage of Russian translation only Took for 8760
Good product and good service. Fast change broken goods. Thank you.
빠른배송에 감사드립니다.^^
I have received the gauge in very good order, it does the job very well , would like to say, it is functioning good. except a mounting screw was loosen, and found that the screw retaining plastic piece was broken, i guess the production may uses pneumatic gun too strong.
Хороший прибор. Есть наиболее востребованные хладагенты. Расчитывает перегрев/переохлаждение, можно проводить тест на утечки с температурной компенсацией, в т.ч. на вакууме. Датчики шустрые, гораздо быстрее термометров с алика за 30р )) Сотые доли (в барах) скачут на нуле, но мне не критично. Вентили немного шатаются, если выкрутить, но работе не мешают. Шланги нормальные, но с дурацкими тефлоновыми уплотнителями. Буду менять на резиновые. Крутой чемодан, гораздо солиднее, чем у тесто. Брал для кондиционеров. Сначала хотел testo 550, но сейчас его делают в Китае и стоит он при этом 25500 (с хлипким кейсом и без шлангов). Проверил на заказе -все отлично работает, все устраивает, давно надо было взять. А тесто зажрались. Доставка -6 дней до Нижнего Новгорода (из России).
С виду все качественно. Термометры точные. Остальное проверю позже.
All Hood
Из России в Москву пришло быстро,буквально 3 дня. Левый(синий вентиль заметно болтается в открытом состоянии, даже по сравнению с другим(красным), В работе пока не проверял.
The goods came quickly. Corresponds to the description
The parcel came in a week in Belgorod. Delivery from Russia. The device is serviceable and corresponds to the description. I am happy with the purchase, the ideal thing for repairing refrigeration equipment. The price is very happy. Seller respect.
miernik bardzo solidnie wykonany. zestaw jest kompletny z przewodami i czujkami temp. działa Ok. Praktyczna i nieduża walizka.Polecam.
Delivery took 4 days from Russia. The device works, there are no adapters under 410 refrigerants. Made qualitatively, in a durable case, looks nice! Recommend!
