Field Worthy
The ProODO instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability. Other tough features include:
Versatile
The instrument provides versatility with numerous benefits from the following features:
Convenient
Connect any length cable and probe to the ProODO digital series instrument and use the convenient cable management kit to keep everything simple and organized. Convenient features include:
Data Manager Software - Free! Watch the Data Manager Demo Video
Data management can become a daunting task over time but with the Data Manager software this task is much simpler and efficient. Download data, configure instruments, and conduct real-time studies easily with Data Manager software. View data graphically or in tabular form and export data as needed to other programs. Data Manager software is a very powerful tool. So powerful in fact, that we give it to you at no charge when purchasing a ProODO . After all, it's all about the data!
When purchasing the ProODO optical DO you will receive the instrument, manual, batteries, communications saddle, USB cable, and Data Manager software. You must order cables separately.
