Model SX721 Operation Manual
Thanks for buying and using the model SX721 pH/mV Meter (the following called “meter" in short).
Before using this meter, please read the operation manual carefully in order to help use and maintain it correctly. On the basis of improving instrument of performance constantly, we reserve the right of changing the content of this manual and accessories in case of not notifying in advance.
This meter is a perfect combination with the most advanced electronic technology, sensor technology and software design The meter can measure the parameters of pH, mV and temperature for high accuracy solution. It is the best portable pH meter with the highest performance and the lowest cost. It is suitable for the trade such as the mining industry, power plant, water treatment projects and environmental protection, etc., especially has more extensive application in the field and spot test.
Builtin microprocessor chip, beautiful appearance, multifunctional and easy to use, this meter has the following prominent features:
1.1. Double parameters meter, equips with pH and ORP electrode,calibration solution and special carrying case, easy to use.
1.2.Builtin microprocessor chip, with the inligent functions of automatic calibration, automatic temperature compensation, data storage, function setting and automatic selfdiagnose, auto power off and low voltage display etc.
1.3.Adopts digital filter and step slipping technology to inligently improve meters response speed and result accuracy.
1.4.Automatically recognize 13 kinds of pH standard buffer solution. User can choose anyone from three series of buffer solutions: Europe & U.S.A. series, NIST series, or China series.
1.5.Purified water and ammonia added purified water pH measuring mode can be set up, for this two special pH measuring modes, besides the general slope temperature compensation, also added function of nonlinearity solution temperature compensation to make measurement more accurate, especially suitable for the fields of electric power and petrochemical etc.
1.6. Meters circuit board adopts SMT filmcovering technology to improve meter’ production reliability.
1.7. Meter has the back light LCD display monitor.
1.8. Dustproof and waterproof meter meets IP57 rating.
