Feature: This ph meter is pen-type model, it has the functions of high precision hold, ATC, waterproof ,precision could be 0.05pH,which suit for lab or outdoor detection.
 
 
OPERATION: 
1.Remove the protective cap. Do not be alarmed. If white crystals appear around the cap. This is normal with ORP electrodes and they dissolve when rinsed with water.
2.Turn the tester ON by pressing the 'ON/OFF ' button.
3.Immerse into solution up to the max immersion level.
4.Stir gently and wait until the display stabilizes.
5.After use, Turn the tester off by pressing the  ON/OFF button, use the water clean the electrode and replace the protective cap.
 
Do not use distilled or deionized water for storage purposes.
 
Large fluctuations in readings could be due to lack of calibration, dry electrode or rundown Batteries.
 
Attention :  during 2-3 weeks, put electrodes in 3mol/L KCL solution for 12 hours, to make sure the reading within accuracy.
 
BATTERY REPLACEMENT  When the battery symbol appears on the display, this indicates a low battery and only 1 hour of continuous use remain. though the unit may continue to function ,the accuracy of the unit will be affected beyond the 1 hour twist open the battery compartment lid. remove old batteries and replace with fresh ones noting polarity as show in battery compartment.
 
ELECTRODE REPLACEMENT 
1.Remove the protective cap.
2.Unscrew the plastic ring on the top of the electrode .
3.Pull out the electrode and replace it with a new one. make sure the gaskets are in
place before screwing back the ring
 
WARRANTY
These instruments are warranted from all defects in material and manufacturing for a period of one year from the date of purchase.If during this period, the repair or the replacement of parts is required where the damage is not due to negligence or erroneous operation by user, please return the parts to either dealer or our offices, and the repair will be effected free of charge.

Mutifunction Drilling Rig

Product Description
The water and air dual purpose series drilling rig is a multifunctional drilling rig that integrates water and air drills. This is the first one in China. The drilling rig adopts an AMT manual automatic transmission. Sensitive and convenient switching between positive and negative. Compared with hydraulic transmission, the power consumption is reduced by 35%, making it more efficient and energy-saving. The drilling rig has a fast speed and can be used in conjunction with a Mud Pump to solve the problem of difficult drilling with a soil gas down-hole hammer. The boring machine has high torque and can slide up and down. Deep hole drilling can be used for hard rock layers, gravel layers, and pebble layers below deep wells. Drill with a down-hole hammer. This drilling rig can be professionally engaged in drilling, monitoring wells, geothermal air conditioning drilling, diamond bit wired coring drilling, and engineering geological survey operations.
The main characteristics of the drilling rig:
1. The drilling rig is equipped with a hydraulic drill tower, hydraulic support legs, and a winch, and the power head can slide up and down. Hard rock can be used for DTH hammer drilling.
2. The drilling rig adopts a long stroke dual speed mechanism and mechanical power head, with a power head stroke of 3400mm, which is used to improve drilling efficiency and reduce the occurrence of blockage and burning accidents.
3. The drilling rig adopts dual oil pumps for oil supply. When feeding, a single pump is used, and when lifting the drill pipe, a dual pump combination is used; Low power loss and short auxiliary time.
4. The drilling rig has reserved some functional interfaces in the hydraulic system, which can be expanded according to the process requirements of different users.
