Stopwatch and timer calibrations are perhaps the most common calibrations performed in the field of time and frequency metrology. Hundreds of laboratories and metrology institutes calibrate many thousands of timing devices annually to meet legal and organizational metrology requirements.
There are three generally accepted methods for calibrating a stopwatch or timer: the direct comparison method, the totalize method, and the time base method. The first two methods consist of time interval measurements that compare the time interval display of the DUT to a traceable time interval reference. In the case of the direct comparison method, the time interval reference is normally a signal broadcast, usually in the form of audio tones. In the case of the totalize method, the time interval reference is generated in the laboratory using a synthesized signal generator, a universal counter, and a traceable frequency standard. The third method, the time-based method, is a frequency measurement. It compares the frequency of the DUT's time-base oscillator to a traceable frequency standard.
Suin SF2002 stopwatch calibrator is an easy-operating and high-precision instrument that adapts the totalize method, which can calibrate electric stopwatches (405,407,408,415/417), mechanical stopwatches and digital quartz electronic stopwatches.
It can not only calibrate one stopwatch but also several ones with several fixtures, which meet different requirements, just like below pictures shown.

USAGE
More than 90% of world industrial production of Urea is destined for use as nitrogen release fertilizer. Urea has the highest nitrogen content of all solid nitrogen content of all solid nitrogenous fertilizers in common use. Therefore, it has the lowest transportation costs per units of nitrogen nutrient. The standard crop nutrient rating of urea is 46 0-0.
The most common impurity of synthetic urea is Biuret, which impairs plant growth.
Urea is usually spread at rates of between 40 and 300 Kg./HA but rates vary. Smaller applications incur lower losses due to leaching. During summer season, Urea is often spread just before or during rain to minimize losses from volatilization (A process wherein nitrogen is lost to the atmosphere as Ammonia Gas). Because of the high Nitrogen concentration in Urea, it is very important to achieve an even spread. The application equipment must be correctly calibrated and properly used.
Rattan cane webbing is a handcrafted product. The artisans select the straight and soft rattan cane to weave into the webbing. While weaving, the artisans have to calibrate the net meticulously to make each pattern uniform in the net. Therefore, it takes more than 10 days for one artisan to knit a long rattan webbing sheet with the dimension: 45 centimeters wide and 15 meters long. The final product is beautiful and durable to the time. Moreover, this product is easy to clean and maintenance.
