65,000.00
A water trap is a device that removes moisture from gas or air streams to prevent equipment damage or product quality issues. It uses filters, desiccants, or condensers to trap moisture, which is collected in a reservoir and drained periodically. Water traps are used in various applications, including gas chromatography and air conditioning systems. Proper maintenance and cleaning are important for effective and efficient operation.

PETROLEUM-SPIRIT 2.5L

18,000.00
Petroleum spirit is a colorless or slightly yellowish liquid fuel derived from petroleum, composed of hydrocarbons with a boiling point range between 30°C and 205°C, with a density of 0.71-0.78 g/cm3 and a flash point of -40°C to -60°C. It is used as a fuel for internal combustion engines and as a solvent for various applications, but it also poses significant health and environmental risks. Its octane rating determines its ability to resist knocking in an engine and ranges from 87 to 93 in the United States.

Andon BP Machine

18,000.00
Andon Bp Machine monitors have a measurement range of 0-299 mmHg for systolic pressure and 40-199 mmHg for diastolic pressure with an accuracy of +/- 3 mmHg. The cuff size can vary, but most come with a standard-sized cuff that fits arm circumferences of 22-32 cm. Andon blood pressure monitors typically have a large, easy-to-read digital display and can be powered by batteries or an AC adapter. Memory functions are also common, allowing for the storage of multiple readings to track blood pressure over time. Additional features, such as irregular heartbeat detection and date/time display, may also be included depending on the model.

PH Meter (Pocket)

18,000.00
The PH Meter (Pocket) is used to measure the pH level of a solution. It is small, portable, and easy to use, consisting of a probe that is inserted into the liquid to be tested and connected to a digital display that shows the pH reading in real time. Pocket pH meters are commonly used in various applications such as testing the pH of soil, water, or food products, and in aquariums and swimming pools. The pH range of a pocket pH meter can vary, but most models can measure pH values from 0 to 14, covering the entire range of acidity and alkalinity. Calibration of the device using standard pH buffer solutions is required before use.
