DaqLink 4-Channel

DaqLink

Specifically designed to incorporate the needs of field logging, the DaqLink data logger enables reliable, accurate and continuous data monitoring.

The DaqLink built-in sensors support standard temperature and humidity environment monitoring needs and an extensive range of data acquisition requirements are also accommodated with four external sensor inputs for PT-100, Thermocouple J, K and T, 0-1 V, 0-50 mV, 4-20 mA, Contact, Frequency and Pulse Counter. This broad range of universal inputs allows for multiple combinations of sensors specific to customers’ applications.

For independent data monitoring the DaqLink features include:

• Rechargeable battery
• On-site data monitoring with two-row graphic display
• Intuitive keypad with Run/Pause logging option
• 16-bit data logging resolution
• Real-time data streaming to PC or storage to onboard memory for later download
• Immediate response alarm alerts
• Audible alarm buzzer
