Brief introduction
JK3000 is a high performance, low price temperature recorder. It can watch multi-channel
temperature changes at the same time.It is very suitable for application of temperature
acquisition and temperature recording.It has the RS232 interface to upload data directly to the
PC, and also has the USB interface to save the measured data directly to the U disk when it is
inconvenient to connect to the PC, and then transfer the data to the PC when needed.It is a half
frame wide host with a top 64 channel direct slot on the back of which can be measured with a
thermocouple, and 1 infinite expansion slots, which can be assembled by a module.Whether
you need only a few simple data recording channels or hundreds of thousands of performance
channels, you can meet your temperature collection at a reasonable price.
3 different types of thermocouple measurement
Measurements that can be dependent on the temperature recording software
The unique design allows every 8 channels to be configured for a single unit, so as to
achieve maximum flexibility and quick and convenient setting of automatic range conversion
inside. That is to say, choose 1-8 as K type thermocouple, 9-16 as J type thermocouple, and
change configuration according to needs.
Here are 64 direct access slots and 1 infinite expansion slots on the back to meet your
unique needs. You can only buy the parts you need at that time, and then add more modules
as your application develops. 1.5 rack units can be used to measure up to hundreds of
thousands of inputs.
Free software simplifies data acquisition
If we require data recording capability based on PC, but we don't want to spend time
programming, software can solve this problem. With this software, you can set up your test,
collect and archive, manage and measure data, and display and analyze the data and curves in
real time. The familiar electronic table environment can be easily configured and controlled for
testing. Rich color graphics provide many options for displaying your data. In addition, using
software can easily send data to other applications for further analysis, or include it in your
display and report.
A brief introduction to the module
The module can be directly used to connect the infinite expansion slot to the back of the
instrument and connect the thermocouple line.
When you need more modules, you only need to connect to the reserved slot of the first
module.(this function is especially practical when the instrument and the need to be far away
from the measured point, not only can reduce the measurement accuracy caused by too long
thermocouples, but also save the large amount of money cost needed for the purchase of
thermocouples).

U disk: the instrument does not connect to PC. It can store data on the U disk, and save data
permanently in the computer by transferring data.
The 3000-8 in Table 8 is that the acquisition module with 8 channels can be used in conjunction
with each of the above instruments. After the customer has purchased any instrument, if you want
to increase the acquisition channel, the 8 channel can choose 108 modules for one unit.
In table 10, 3000+108 indicates that customers can choose how many channels to collect
temperature according to their needs and choose a 108 acquisition module with 8 channels as a
unit in the case of a host. If you need 80 channels, you can choose a 64 way host and 2 108
acquisition modules.
