Microseismic geophone

Microseismic geophone is mainly divided into shallow well type microseismic geophone (VHL5) with aluminium alloy shell and explosion-proof microseismic geophone (MA1, MA3) with stainless steel shell.
  • - The corresponding waterproof treatment of the metal shell makes it meet the requirements of shock resistance and waterproof.
  • - It can be used in harsh working environment and can be easily reused.
  • Detailed introduction

    Microseismic geophone is mainly divided into shallow well type microseismic geophone (VHL5) with aluminium alloy shell and explosion-proof microseismic geophone (MA1, MA3) with stainless steel shell.

    The corresponding waterproof treatment of the metal shell makes it meet the requirements of shock resistance and waterproof. It can be used in harsh working environment and can be easily reused.
