WZZ-2A automatic polarimeter is a general-purpose polarimeter with ±0.02 Degrees Optical Rotation accuracy. The instrument is applicable to food, university education, chemical and fragrance applications. 　 Features: The instrument has an auto-control system, Switch on the power, the system will automatically search an optical zero point. Place the sample tube into the measuring field chamber, the instrument will shows measured value immediately.

GasAlertMicro5 PID photo-ionization sensor detects volatile organic compounds or VOCs and can be added to a standard four gas configuration or combined with non-standard combinations of other sensor. Add the attachable/removable sampling pump for confined space entry or remote sampling GasAlert Micro5 PID portable gas detector simultaneously monitors up to five atmospheric hazards including volatile organic compounds (VOCs), oxygen, combustible gas (% LEL), and a wide selection of individual electrochemical toxic sensors. Compact and lightweight, GasAlertMicro5 PID activates audible, visual and vibrating alarms in the event of a low, high, TWA or STEL alarm condition. VOCs present multiple potential threats in the workplace environment. VOCs are characterized by their tendency to evaporate easily at room temperature and include substances such as solvents, paint thinners, benzene, butadiene, hexane, toluene, as well as vapors associated with fuels such as gasoline, diesel, heating oil, kerosene, and jet fuel. The GasAlertMicro5 PID's integrated photoionization detector (PID) enables sensitive broad spectrum monitoring of volatile organic contaminants. Highly configurable to...
