The ec dipstick is one of the easiest meters to use, providing the 4 most popular scales: ec, cf, 500:1ppm, and 700:1ppm!
The ec dipstick dissolved salts pen operates on 3 common inexpensive aa alkaline batteries.Measures in ppm, ec and cf scales. No calibration required. It calibrates itself each time you replace the batteries.
The main idea behind all meters is for you to mix your plant food in your water and take a reading, then log that reading for future use.
If you want to quote numbers, look to the international ec or cf scale for your numbers (cf is 10 times ec). Ec stands for electrical conductivity. Simply note where the light blinks and your done.
The curves and characteristic parameters on vulcanization of rubber materials can be obtained using rotorless Rheometer based on the measurement of the torque exerted by the rubber material on the oscillating die.
The MRC3 Rotorless Rheometer has excellent property of reappears and stability. In a test with good mixed rubber and the timerange is 12min, the T90 may be several second difference in 4 continual experiments.

This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement parameter. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of
Inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive dsp processes and calculates and then
Outputs the measurement results on lcd.
