All the brands suggested are good but you will need to assess what will be best for you. For example, cost, how portable do you want it for ease of transport and deployment, what accuracy and precision you need, how robust, calibration frequency and ease, do you need a data logger, etc. Best to look at the specifications of each and then decide.
