K-2000 type digital multimeterDetailed product description：

The 2000 model six and a half digit multimeter from Jishili Instrument Company in the United States is a fast, low-noise, and fully functional six and a half digit multimeter among similar products, but it is only equivalent to the price of a five and a half digit multimeter.
The 2000 model adopts high-speed and low-noise 28 bit A/D conversion technology, and uses special servo front-end technology, which makes the meter have the characteristics of high precision, high linearity, high speed, low noise, and low drift. Due to the use of annual mounting technology and single panel design, this watch has extremely high reliability.
The 2000 model has a thermocouple direct temperature measurement function and a unique multi-channel scanning card Fujian, which can patrol 10/20 different signals. Weak countries can conduct more road measurements and can also be paired with Keithley's 7000 series programmable switch system to form a multi-channel, multi parameter automatic measurement system.  

Main features
Fast speed: 2000 readings per second (four and a half digits); 50 readings per second (six and a half digits)
Low noise: 5-10 times improvement
Memory: 1024 readings
Multi channel scanning measurement capability: optional 9-channel thermocouple temperature measurement card or 10/20 channel scanning card
Equipped with IEEE-488 and RS232 interfaces
Programming supports SCPI commands and can simulate Keithley 196/199 and Fluke8840A/42A commands
Testpoint and Labview drivers
Three year warranty
