ZYD-1 automatic permanent stop titrator

Brief introduction
This product is an indicator instrument for determining the endpoint of diazotization according to the Chinese Pharmacopoeia 95th edition. It uses an electromagnetic valve to control the on/off of the burette and has both manual and automatic functions. All of them use touch switches, making it a powerful tool for capacity analysis in chemical laboratories, drug testing institutes, hospitals, pharmaceutical factories, veterinary drug factories, and other pharmaceutical and chemical industries.
2、 Product Features
1. Used for diazotization method determination, it can accurately determine the twenty-two samples specified in the pharmacopoeia
2. There are two operation functions: manual and automatic. Manual operation is convenient for adjusting the valve flow rate and dropper zero line; Automatically drip to the endpoint without supervision
3. There are two sets of electromagnetic valve devices, and the standard solution flow rate has two speeds: fast drop and slow drop, which can be controlled
4. Install an electrode current reverse protection device, with the electrode fixed within any range of 360 degrees, which can accurately titrate the endpoint
5. The speed of the mixer can be infinitely adjusted Equipped with endpoint light indication, buzzing sound, and automatic locking device
