About this item

Aw Range: 0.003-1.000 water activity meter price can be used with some products (mostly synthetic products) as a means of indirectly measuring the total moisture content

Accuracy: 0.005Aw This requires developing sorption isotherms to this purpose

Resolution: 0.001 Aw Sorption isotherms are graphs that provide the relationship between water activity meter price and moisture content at constant temperature

Test temperature: -20 to 85 degree For most natural products, repeatable sorption isotherms cannot be reliably developed and water activity meter price should be regarded as separate from moisture content

Work Enviroment range: -10 to 60 degree, Humidity 0-90% ontent. This requires developing sorption isotherms to this purpose. Sorption isotherms are graphs that provide the relationship between water activity meter price and moisture content at constant temperature. For most natural products, repeatable sorption isotherms cannot be reliably developed and pawkit water activity meter price should be regarded as separate from moisture content

Calculation

Formula: RH = (V - V₀)/S

RH: Relative humidity;

V: Voltage value corresponding to the measured substance's activity;

V₀: Zero-point value;

S: Slope value.

Substitute the activity values of saturated potassium nitrate and saturated sodium chloride solutions, along with the existing zero point and slope values, into the formula to determine the voltage values V_(potassium) and V_(chloride) for measuring potassium nitrate and sodium chloride activities:

90.3 = (V_(potassium) − 0.848) / 0.030726, V_(potassium) = 3.60 V;

80.5 = (V_(chloride) − 0.848) / 0.030726, V_(chloride) = 3.32 V.

 

Calculate the new slope and zero-point values:

Standard activity values: RH K = 93.6% RH Cl = 75.3%

From the formula: S = (V_(K+2) − V_(Cl)) × 1000 / (RH_(K+2) − RH_(Cl))

1) S_(new) = (V_(K+2) − V_(Cl)) × 1000 / (93.6 − 75.3)

= (3.60 − 3.32) × 1000 / 18.3

= 15.30

2) Substituting into formula RH = (V - V₀)/S: S/1000 = 0.01530,

RH Potassium = 93.6 V Potassium = 3.60V

4.25 - New V₀ = 93.6 × 0.01530

New V₀ = 2.82V

Enter the new slope S=15.30 and new zero point V0=2820 mV into the host computer to complete calibration. Specifically, repeat step (1) by modifying the instrument settings: change 848.00 to 2820.00 and 30.726 to 15.30, thereby finalising calibration.

Features:

The active part of moisture content and, therefore, Water Activity Meter for food, provide better information than the total moisture content regarding the micro-biological, chemical and enzymatic stability of perishable products such as foods and seeds. For similar reasons, Water Activity Meter for food is equally relevant in the pharmaceutical industry where it provides useful information regarding the cohesion of tablets and pills, or the adherence of coatings. water activity meter can be directly compared with the relative humidity of the ambient air to prevent dimensional changes in a product (paper, photographic film), to prevent hygroscopic powders (powdered sugar, salt) from caking or turning into a solid block, etc
